You could go to the stats page
The 47 Ronin - Players and check out the map performance section to see where you die and get kills you will get a clear picture of your strong and weak areas and what you need to work on as far as playing to round out your game, also your weapons stats as well you'll see your accuracy with each weapon ect. and could use that information to keep in mind for certain situations you might find yourself in.
Now that only gives you a by numbers look on your play style although it definitely shows your weak points and what you should work on. The hardest part is getting out of your "comfortable" zone. Like players who are can awp but cant rifle. From a competitive standpoint that may work given that you as a team is able to keep that afloat by winning rounds(money)
Confucious brought up a great point. your sensitivity plays a part too, you may play with one you feel is right but it may not be what you need
Your cross hairs too from size to color plays a small role but can mean a difference from frag or a death.
For me this works wonders as you have the cross hairs with the dynamic settings that open and close as you move and shoot as well as an outer cross hair that is small and transparent that show where my shots may hit during a spray or on the move.
My settings are
cl_crosshairalpha "99999"
cl_crosshaircolor "4.000000"
cl_crosshaircolor_b "0"
cl_crosshaircolor_g "0"
cl_crosshaircolor_r "0"
cl_crosshairdot "0"
cl_crosshairgap "-0.7"
cl_crosshairscale "1550"
cl_crosshairsize "2.3"
cl_crosshairstyle "4"
cl_crosshairthickness "0.9"
cl_crosshairusealpha "1"
There are also good aim maps to warm up on
Steam Workshop :: training_aim_csgo_fixed
Has plenty of different settings you can choose from and definitely worth a try.
