i prefer the first one. The second one looks like a failed attempt at realism (no offense) the First one looks more unique and stylish.
I think you have improved, your hair shading looks very good, I like it a lot!
I prefer the second drawing more than the first.
I do have a bit of critiques on the second one, but I’d only critique if you were okay with that. Both styles seem great for commissions in my opinion! I think if you did commissions you’d have a lot of interest.
