Inking practise

I'm trying to practise a bit on inking on a smaller scale, so I inked a few sketches I already drew a while back.
Seriously need to learn to ink better, the top drawing is the best I got so far. They should show on your screen at about the same size as they are in reality. (or actually, they're shown a little larger here)
They're all inked with indian ink and a brush, and the woooonderful colors were added in MS paint.
