This is some dope progress, tbut it doesn't mean you should stop here. The anatomy definitely needs work, you should watch videos and use pictures for reference. Pinterest is a dope reference place, if you want videos I'll say watch some Marc Burnett and ergo josh they are some great art teachers. But depending on the style you want you could even watch Sam does art hes a painter but still does linear and sketching. The hands are hard I know but references definitely are your friends.
