Have you done any sketch before? If not then it is very good work, there are few reasons why:

• you just grabbed a pencil and did a sketch

• I do not know if you noticed but you have chosen difficult parts of human anatomy hands and feet. Not many start with such difficult part because there are a lot that could go wrong but when people just start without knowing that then our brain does not think and we just do

• both hands are well done, the proportions, the position of fingers

I think if you add shading paying attention to the light and shadows that will give the impression of three dimensional object

I am very impressed with that.

We have a great Artist on Steemit, @jorgevandeperre, who did and does a lot of teaching in basics of Art, I wonder if he will find it interesting to join this community too, he professional advice will be great.
