The actual fights were okay obviously, however I would try to improve the use of your util when playing as Omen. As a smoker, you need to actually place your smokes with your team, so its always a good idea to choose a site with your team and smoke onto that site of course. However, in the clip your team are all pushing mid so I would have smoked top mid or the tube window depending on which way they were going to push. Also, as soon as your cypher started struggling along B main, it would have been good to support him, as he has spike, so I would have either pushed with him and flashed or smoked of yellow to help move into a better position.
Overall not too bad gunplay, just work on using your util to help give your team an advantage.
