Angel001

oh cool i've seen your feedback on other people's artwork. I like how you don't shy away from capturing definite forms here! I have a liking to an anime-esque style as well and this reminds me of angel beats almost!!!

For the face, it makes the piece look flat due to it not exactly following the same depth of the figure. So, I would revisit the planes of the face and how certain angles contour it. If possible, you could reference cell-shaded anime-esque 3D models in video games to find how they simplify the face in three dimensions. My recommendation is to look at Persona 5 models since there are online catalogs of them!! 

In relation of the head to the body, you would not see the neck that much in relation to the head because it's bending to follow the neck. The head and neck work in tandem of each other!

Below I've drawn over your art with a base guide in how I would edit the head to match the anime style :D

good luck and keep going!!! <3

you already do something that will lead to amazing results with practice. you are shortening the proportions. but it takes practice to get it right from any angel. keep working with references till you got it!
