Hello and welcome

Okay, first:
You need to take your time and be precise. The eyes arn't really circular, you should try using the marque tools when your painting, it will make your job a lot easier and a lot more precise (Good job on the teeth but not as well on the eyes, did you start with the teeth?)
Again, you've forgotten some grey paint around the mouth, patience again

Did you follow tutorials or was it just mind made?
I, strongly suggest you follow tutorials or if you can get a teacher, even better. That way, yo'll be going deeper and deeper into photoshop, learning filters, layers, blending modes and so on.

Anyways, I see some potential, keep it up!

no i didnt follow anything, my eyes in general arent very circular
and i didnt use grey paint at all..i used sponge and burn tools.

as for teachers and tutorials i dont really have either, i was thinking of taking some classes at college when i start tho..ill keep working tho, thanks for the comments
