First things first, credit where credit is due, check the sketch that I didn't do justice at all with this experiment:

So yeah, just practising here. I looked for a way to smoothen the lines after the fact. I found a way to do it while you're drawing them. Since I didn't want to do it all over, yeah, the lines are kinda crap.
The flat colours are fine, but the shade. I used the sketch as a guide for the most part, but I have no clue what I'm doing with shades.
And the few highlight lines. I don't know if they work. I've seen things like that around, but I don't know what I'm doing there either....

Still posting this... ;)
