3D VoxelArt Character

Soooo … I’m making a 3D game (Should be some kind of MOBA KitPvP but for the art that’s irrelevant :smiley: )

The problem is: I’m totally too bad on making good Character Models.
The whole Game should be Voxel-Based (to make it easier to generate a limited random world the players can interact with, e.q. Cutting down Trees, collect Berries etc.)
Creating some Example Trees is quite easy, getting generated by the Server randomly (Same with Bushes for Berries etc.)
But for Character Models that won’t work (For Monsters or Animals that run arround neither) so i made myself an editor that lets me create Voxel Models and export in a format that saves space and lets me load them very simple (Into VBOs). There’s 2 Files the Editor produces: the Geometry Data containing each Voxel’s Position and Color (For Modelloading and -Editing purpose) , and the File that gets used for loading the Model, it just contains the Color, Normals and Vertices for only the faces that are Visible, so Cubes inside of a Model get Lost in this Format.

So well, Can anyone show me a good Tutorial for 3D Voxel Characters that don’t have too many vertices? or Any ideas how to Improve Mine cause i think it doesn’t look too good: ???
