I see white bits on the screen....
Aswell the lines look like it is a sketch but with colour, make work on trying to do neater lines and not letting them go into another part of your drawing, but it’s still pretty good, maybe start working on shading aswell like I am, shading can make the art stand out. I am not hating on this piece of art, I still think that it is very well drawn. its a good choice of colours that fit in well with the background.
