The first thing that jumps out at me is the outlines. You should get rid of them. Draw in tones, values. Put in the black shapes around the hands, the mid tones, the highlights, but don't draw lines, just shapes. Nothing in nature has outlines. Also, these appear to be a little rushed. Take your time, really study what you're looking at, double check proportions, negative space etc. A classic read is 'Drawing on the right side of the brain'. If you go through that, takes about a month or so, that would improve your basic technique no end, then drawing everything will be ten times easier.
