Sopranos sketch

I feel quite happy about how this turned out but I would like critique on any ways the form or way the features sit on on the planes etc might be off. Also things to consider when constructing the head in this way would be helpful. Tips on linework or rendering with biro also appreciated

Gas Giant

Having a hard time with getting the fore/mid grounds looking right. Cannot draw grass for the life of me, and the telescope looks off, I'd appreciate any help!

I'm really struggling with the features and the head. It felt like something is off here especially the 3/4th head.

Fancy Dwarf Guy

This started out as a practice in unique head shapes and turning them in space, but it turned into a dwarf guy in a bow tie. Is the perspective working out? Any other thoughts? Thanks

Redraw of an old piece - yandere bunny Belphie

Decided to go with version B based on feedback. Changed the angle a bit. Rough sketch before rendering. Could use help with anatomy >.<
