I can't tell whether those shades on the dress is a pattern texture or actual shading. If it's the latter then you should think about where the creases on the dress would actually be and where the shade would be in relation to the lightsource.

Wewnętrzna strona skrzydeł jest po prostu cudowna, ale jakoś ta pracka mi się nie podoba :( Pillow shading na skrzydłach (brązowe) i diaboliczna smutna twarz. 4-/6

I dont like it very much it looks alittle Odd.

it doesn't really loook like an angel in my eyes and it's very pillow shaded
