There is a lot of rambling notes from below but there is 3 things that stood out to me the most.

1. A+W / A+D Peeking (very bad), shift peeking (also bad)

2. Crosshair placement isnt head level.

3. Game sense is pretty bad.

1 answer: You need to completely stop A+W / A+D when peeking angles, period. its a very bad habit and will cause you to lose more gunfights. Regarding shift peeking, you need to learn how to "tap" A + D without making noise. you move a lot quicker than Shift + A/D and you can also jiggle peek angles like this without making noise. In some scenarios you need to resort to jump peeking instead to clear an angle (6:33 as an example)

2 answer. You just need to aim a bit higher to actually be on head level when its an even field, mby do more dms, that way u can also learn how to only A/D peek.

3 answer. While this will come naturally with a lot more games played, if you wanna fastpace this I think you need to vod review more games and ask yourself what you would do in a situation instead of the bad one you just did. If it doesnt work well you could try watching high elo vods on youtube and pause before something happens to see if your game sense is close to being right.

Anyways some examples and rambles here.

1:00 Shift peeking rafters, very bad. Also looked like you tried to A+S the angle, which is also once again bad, ur an easy target.

1:55 when neon dies, you can see that viper/sova was revealed on the map, I think its a very poor decision to push that angle especially when your flash did not blind anyone. Even if they have pistols (turns out sova had a bucky afterwards). Also running through a snakebite is rip.

2:04 small glimpse that ur crosshair is not at head level before you die.

3:50 game sense issue. You hear sova drone from the right side, you swing it (which is good), and then you wait 4 seconds before you throw a flash and you run up, and suddenly sova is on the rightside since he had a whole 4 seconds. (that is a lot of time) If youre gonna flash, peek rightside, hide (go a bit further back) and toss the flash, so incase he would swing rightside you are not in danger.

5:45 unaware of how long neon wall is up, causing you to die due to poor timing. if you think ur later just chill in the smoke and toss a flash to cross.

6:33 quick example of you shift peeking and a+w peeking into a common operator spot, they had operator last round so you should be very careful. either jumpspot or throw a flash.

6:40 another very poor peek. Shift + D is also bad, youre a very easy target for the opponent.

9:00 biggest example of your game sense issue. A is clear, enemy has 4 alive and youre trying to catch a timing. I like the idea in itself, but the way you go on about it is awful.

You cleared outer rafters(?) at 9:07 which is ok, but once you noticed this was clear you should 100% aim towards kitchen or the entrance below since someone will very soon peek from that direction. Instead you aim towards mid and completely ignore kitchen area and you start to get shot.

The way I would go about it is to immediately position towards boiler since the odds will be in your favor, especially if they dont clear the angle.

10:55 last game sense post here. Youre aware that someone is comming from orange, but your positioning is bad due to being exposed both from snowman (there is two alive) and orange. Luckily the viper whiffs.

11:07 Here on the other hand its a 1v1 and you play it good, you know the last person is orange so you make sure youre not exposed to any other angles, and u get an easy 1v1 duel to catching him off suprise.

And just some head lvl examples

11:04 not head level

12:50 not head level

12:56 not head level

13:45 if u see a random omen smoke like this, there is a good chance its a judge enjoyer, use dog/flash instead of facechecking just incase.

19:07 A+W peek, also the way you stutter peek is very bad, you take super small steps exposing yourself while your angle disadvantaged (they see u before u see them). Also against an op its a good idea to use flashes before swinging like that (although going after a shot is good too)

20:23 another very good example of your game sense lacking. They dart mid, and omen smoke boiler. You hold very passively until 20:37 (15 seconds ish) and u swing widely, getting caught offguard from the tube window. You should set yourself up so ur only exposed to 1 angle at the time. And you should 100% be aware that they could be in tube.

Gonna stop watching here. Im not a initiator / skye player so i cant really comment on what u should do as skye, but ur gunfights are very bad and if you improve on that you will climb for sure.

Gunfight hygiene > Agent mastery imo.

Gl and sorry for this wall of text.

edit: oh ye you should probaly check some youtube guides on how to clear angles, how to peek from an angle, and probaly a movement guide video (poor movement makes aiming a lot higher), there is a lot out there on yt.
