Your eye for shading and texture is fantastic! perspective, proportion, and anatomy need work.

I like the clothing that your dude guy is wearing. His face is really well-done too.
The shading on Link and his clothes look fantastic. It's funny that I noticed he kinda looks cross-eyed... but then I remembered that when I was playing TP, I always thought Link looked a little cross-eyed. Makes him look wimpy to me (because of Nintendo's design, not your drawing).

I'd never have the necessary patience to do a MSpaint Line drawing like that!
