Ok, first of all, I would like to say sorry for the crit I gave on some elses sprite thread. It was crap, and had I had just come out of an op, so I had no idea what the hell I was doing.
Must have been hell for you to read it.
Anyways, This example I did might help you.

Obviously, bieng then a better spriter, you may have done the legs differently, but I think colored in it would look quite good. I moved the right foot down, and add a bit of leg, and making, I suppose 'thigh' smaller.
The perspective is hard to work with, but I think you've actually done a pretty darn good job.
Also, you first work is amazing! The pixel overs are brillant, I never seen them so detailed! Love 'im.
Hopefully, I didnt put rubbish advice this time.
