first off, I love your style. The hands are done wonderfully, and the proportions are on point. Though the shading is a bit off, as I can't exactly tell where the light is supposed to be coming from. The backround is blank and doesn't add anything to the picture (I'm not too good with this myself, but trying is key.) The lines are a bit shaky and rough in some places, but overall, this is a really good drawing. Keep working at it!
