Yes, I do use blender, and I enjoy using it! Could you give me some more tips? I'm more of a beginner at making Blockland specific models (I have been making some FPS's on Blender too :3).
Yeah i can give you some tips.
Tip one: Draw all of your concept art out on paper.
(Or at least in a imaging program)
It's good to have the proportions sketched out ahead of time.
Tip two: Spend time making your model. Don't feel rushed.
It took me 8 hours to model some of my latest work.
Tip three: Have pride in your work, but still be open for suggestions and constructive criticism.
