I wish Dwarves had bigger legs. Personally I feel right now they're too top-heavy and nor proportionate to how I feel they should look. Dwarves being sturdy and hard to knock over makes the skinny legs feel a bit out of character. The torso could have also used some work.
This particular drawing by itSMEneon is what I personally think would be ideal proportions. Obviously at this point it's probably too late in development to make these changes without having to redo all the armor/clothing/animations. I'll make do.
