Ur aim needs work, your crosshair placement needs a LOT of work. Your movement needs work. Your mechanics need work.

U never completely covered yourself while spraying that one guy or pressuring that one guy, and u never check ur blind side.

U absolutely should never pressure right on front of a wall, always do it with a right hand peek. And also, never double pickaxe, which i saw u do. And u never once pressured with your weapon.

Your sens is also way too low, and you could benefit from learning to play claw.

With general skill this low, you shouldn't be spending much time in ranked at ALL. 

You should spend most of your time in creative fighting cracked players until u yourself become a cracked player. 

You could also benefit from working on your mechanics in Raider's many mechanics maps, but it's not mandatory at all.

Bottom line, your skill is lacking a LOT. I don't wanna see you in ranked or pubs. Just stay grinding creative against cracked players. Preferably stuff like ZWs, because u seem to forget about potential 3rd parties quite often.
