Ok. To be honest, a lot of things are wrong here. Your proportions are off(compare the head to the body). The eye and lips are also extremely large. But seeing as this is anime inspired that's to be expected to a point.
The pose is dull(very stiff) and a lot of the body is hidden. I'm not aware of your habits but try drawing as much of the body as you can. That will help you with proportions as well. Also the ear in the background is very high making it off perspective.
The muscles on the stomach need shading as they come off as undefined. You're coloring looks rushed and messy.
Now don't take all that the wrong way, you're still ahead of a lot of other people. My advice is when doing character designs, draw the entire body. Even if the focus is just the face. As you get more comfortable with that try new poses. Find a method to your art, it seems you just kinda draw without worrying about measurements or perspective. Even if these aren't your strong suit, understanding them always make a better picture.
Don't worry about color right now, just shade with a pencil(or pen) so you can get use to values.
Keep trying, and take yourself more seriously if you're gonna present a piece. Saying you were "too lazy" to add something reflects very badly on you.
