While i am okay with a droideka in any good looking shape, i do wonder how it would look like if you did it in a more Blockland style, like the battledroid from Tophius.I am not saying that droideka is ugly, not at all, it is awesome!
It would probably look better if the point was a bit rounder and the back a bit longer.But not bad!
I really really like this item. It would be cool for RPGs
