ok! anyways, to start of the hair is done nicely, i see ya tried that kind of realistic thing but i suggest to not add too much of those "lines" its pretty distracting but then again maybe its just an affect- i dont know lmao anyways second of all the grass in the ocean section the ones at the back need to be lighter, try not to make the shading too dark you can might as well look at refrences for wings for the angel side dont get me wrong, its nice but the lines on the wing are really shaky

i hope it helps! and no problem
