I think it looks fantastic! You did a really amazing job with the coloring, and the hands look fine! With your coloring, a few little bits of highlights or detailing would probably make them stand out more.
Oh- it's a type of painting style that is sorta realistic, but instead of incredibly realistic it uses more of un-blended brush strokes and the like. Monet used it in his paitings. Hey, just keep practicing and experimenting and you'll find one perfect for you!
