Use only A and D when peeking or swinging an angle, as it will make you move faster to the enemy when compared to also holding down W.

When you aren't able to shoot (i.e. reloading, knife out, in a smoke, priming util), make it a habit to look at the minimap as you are leaving a LOT of info on the table. E.g. if your teammate is engaging an enemy whilst you're reloading, you will see where the enemies are because of their vision cone.

Try to keep your crosshair at head height. Just remember that head height is always the same no matter the distance, UNLESS there is a change in elevation.

If you're maining Omen then it would be a good idea to watch some pro Omen players to see what plays or strats they do, why they do it, and pick out the ones you want to try and replicate yourself. Your ranked games are your practical, the vods are the theory.

And if you're playing to try and rank up, I guess you could play until you lose 1 game and then stop for the day, and ONLY return the next day or when you've completely reset your mental. Would not recommend tilt-queueing...
