How do I make my dwarves smooth and round?

Solution 1:

If you're using Lazy Newb Pack, the current version has various options which seem to meet your needs. These are found under Graphics, Customize.

I also checked Tileset Repository for large square tilesets, as are necessary to have smooth circles. Hack_square_64x64.png might be the best. Sample in game, and full tileset included below.
