spriting attempt

[Dubzilla]

exams been giving a headache this month, so i thought i would try something i never done before to take a break/relax.
that is when i thought about learning to sprite
here is my first attempt to sprite something, not c&p or mix parts of original characters

i get the template in 1 from davis standing and started to color up. i had a lot of problem with the hair and face, but then i manage to make 2 there.
the face was too davis for me and i edited it to 3. critics/suggestions needed

2 questions What Program Did u use to draw these?
And Did you use mouse or tablet? (like other Spriters do)
