HAND:

The drawing is solid (reference, I guess) but I'd clean up the line art even more BECAUSE I'M A JERK. The colouring is also solid, but it, and the lineart clash in style. getting the lineart cleaner is a first step towards getting them to work well together. Then you need to go in and actually lighten or darken your lineart so that it adheres to the brightness of individual places. The more you can get this to look painted, the better a job you've done (in my oppinion, as this is a very good exercise).

PONY:

Ponies are for fags, you fag. Again could be a bit cleaner. Especially given the subject matter. Your stylistical choices should reflect your subject matter, juxtapose it or otherwise aknowledge it. In this case, going for real smooth all over I think, is a good idea. Also, the lighting on this one is a bit, wobbly. As in, lots of ambient light, but no discernible light source. This presents problems in my telling if it's consistent all over or not, but it's no biggie.

PORTRAIT:

I like the brush strokes, it's a good idea to train different styles, because they're used for different things. Or something. So the brush strokes showing are good, but the glowing is not, in my oppinion. This would be a good piece to try to retain the 'busy' style, but take away lines that aren't essential to it. I'm looking at those in the top of the front of the dress, or in the right (ours) shoulder. Where there's less busy strokes, there's more light. So in the shoulder it'd make sense to take them off, for example. Top of the head also, and so on.

I can see you getting better from piece to piece.
