Sure thing! and....
Welcome to the forums!
In order to help you a bit further I need to ask you a couple questions and you can expand later.
Question 1 - Is this finished?
If yes - great! congratulations!
If no - Is there an artist style you are trying to make your finished artwork look like? Can you provide an example?
Question 2 - Are you working on separate layers for the elements of the artwork?
(i.e.-line work/flats/hair...etc?)
If yes 1- I think you would benefit from doing just a little bit of cleanup. Its fine to use symmetry mode! But that line work still having those "errors" on both sides makes us see it twice...
If yes 2 - Also hair overlapping the wing would add some spacial effect, with the illusion of depth and the line work would look really cool - because you emphasize the shapes that the human brain needs to build the quick read and illusion.
If no - It might get a little hard to clean up but its not impossible. Consider using the cleaned up line art layer -or line work- as the reference for your flats layer.
Technical Critique Overall:
You are only a couple steps away from adding a light source and composing a mood with composition and color. Cool stuff.
Objective Critique
Great place to start.
Naive and Fresh are words that replicate safety - and simplicity. Anything with a sharp or hard angle will make the human brain fight that idea. Things like the feet and hair tips and wing tips, and the corners of the eyes. These elements of the piece enforce the overall shape language idea first for our viewers. Making us feel opposite of what you probably wanted or intended. But they are certainly easy to fix at this stage!
Overall
