that looks like it would be fun.  What is the object of the game?  Eat humans?

I actually like the white skin and pale, desaturated colors.  It gives it a dreamy, whimsical feel.  I agree that we should see some backgrounds though.

Perhaps you should spend some time getting a sense of your perspective.  Mockup a very simple tiled world, maybe like a chessboard.  Add a few walls and an archway.  Make them super simple to save time, just a bunch of blocks.  Then make a cylinder that is the size of a person, or maybe make this before you do the mockup.  Either way, make sure that the proportions match.  The cylinder should look right standing on a tile, it should look right next to a wall (it should be shorter than the wall), and it should be able to fit through an archway.  Multiple cylinders should look right next to each other, because you want a crowd of people to look right next to each other.  How tightly they cluster, how much the top of one overlaps the one in the tile above, etc... make it all look correctly proportioned.  Adjust things until it looks good.

Then draw a person inside of that cylinder.  The top of hit head should be the top of the center of the cylinder.  His shoulders (or her hips) should touch the sides of the cylinder, the feet should touch the bottom.  If you did everything correctly it should guide you to the right proportions.  You might want to start from the bottom of the character.  First start by drawing his footprints in the ellipse that represents the bottom circle of the cylinder.  Then draw his feet and legs.  Draw his waistline.  It should be an ellipse of the same shape (not size) as the top/bottom of the cylinder.  It should probably be about halfway up the side too.  Then keep drawing the upper half of the body.

The colors and textures of the vegetation in combination with the rocks remind me of a beautiful book that I owned, one about dinosaurs.  I love the clouds as well.  I'm excited to see more.
