Dark Angel

I love your lighting and character, though you used black to give shade to the clothing. Your light is also coming from the top right corner, but you've shaded the clothes as if it was coming from the front. When you're choosing a colour to use for shading, move the colour picker diagonally until you reach a tone clearly darker than the normal tone. 
Sorry if the criticism is harsh, but I believe your art has lots of potential! Keep trying!  
(Good job on lighting the eyes though, your eyes are spot on  )
