Hey me-shell!

This was done in Paint tool SAI with the cheapest Wacom bamboo, so solely on computer. I do sometimes start out on paper, scan (if the scanner isn't dead), or photograph the drawing, and then continue in SAI :) Do give it a try, layers are your friends! Just sketch, top up a layer for inking if you wish, and put a layer under, and keep your lines nice while you color under it, as you probs already know. ^^ If not, youtube it.
I can really recommend SAI, it's cheap and doesn't do under for the expensive programs like Photoshop. Only thing is, you can't use a type tool in it.
But those are small things easily overcome!

Love your style too! I'll be following you, too! :)
