Concept sketching practice

Rektum

Hey guys. I’m pushing my concept sketching skills. I’d love to see any feedback you may have. Lately I’m focusing on vehicles(because they’re awesome.) what I’m trying to improve right now is line weight/quality and form design. Thanks for checking out my thread.

This is a UGV(unmanned ground vehicle) design based on some reference I collected
