I used a mouse so it's not very good. Also please comment. My other 3 havent been commented yet.

Please take into account that having a mouse is no reason to be unable to draw nice things. You do not need a tablet to draw well, and different things work for different people.
You should look at LiquidOnyx's Deviant art. He uses a mouse and produces some beautiful digital stuff.

Just keep practising and you will improve and all together it isn't a bad drawing either, I like the colours you've used and the contrast of light and dark. :)

You know what? I work from a tablet and it is MUCH HARDER than using a mouse.

I like it. I use my tablet sometimes and it is harder than a mouse. But everyone works best with different things.
