Aw, thanks... Just a lot of practice. I was a bit nervous because I just drew the hands off the top of my hand, good thing they came out okay *phew*. Just practice a lot of sketching and it will be easy for you, too.
Thanks! A lot of art teachers will tell you that you should always use your biggest brushes on the canvas first, then graduate to the smaller brushes as you add detail and refine. I guess I am trying to apply that to digital art, as well?
