The Romulan has pointy ears... well, as much as I could show, the Klingon is slightly chunkier and shorter than the Romulan,,, the pic I used as color reference showed the Klingon as the same size as the Andorian.  I can play with the body types though, it's worth a shot to see what I get.  Thanks.

There's nothing about them that alludes to their species other then the andorian (who is blue). Andorians and Romulans are normally alot slighter in body structer then a klingon, which i think you could still get across even at such a small size.
