My Various amateur attempts at 3D art (more in OP)

Here are some very beginner attempts at 3D art I made for a personal sci-fi worldbuilding project. I knew absolutely nothing about 3D art (art in general, really) until January of last year when I downloaded Blender on a lark and started poking around. Why not? It's free. Texturing and shading is proving quite daunting, so I've been sticking with a more primitive style. Kinda reminds me of the show ReBoot.

The planet Yih. It's kinda like Earth, 'cept it has a ring.

Wind fruit. It auto-ferments in your gut and makes you drunk.
