Lel ikr. Regardless, let me pick at some things.
Im not too sure what you're going for. Im guessing you prefer cartoon styled Art. In that case. Don't blue your colors. That's okay for shading and combining two colors that SHOULD be together. Like maybe two tones for the eye color. Or maybe hair colors fading into another. Don't blue your mouth into your skin. It's weird. I like the black shading for the eyes. Just be careful.
Use bold lines when making your art. Not, like, BOLD bold, but a distinct separation between two seperate items (the eye and the hair per say)
If you're wanting a new program that is free after your trial expires, download Gimp 2.8. It's the next best thing in my opinion. Many artists use it here.
