can anyone give me tips on how to draw form? my stuff always ends up looking kind of flat. (yes i know the head and face are a bit confused)

Maybe as practice you could have the subject facing more to the side, and move the viewer closer. That way it'll be easier to notice if the features are really placed on a sphere, like if the eyes are different sizes. The hair has lots of potential depth, but perhaps a hat with flaps and a sawtooth pattern along the edge would be easier to apply perspective to and see if it's correct.
