all of them are slightly to abstract to me but i would say the last is my favorite and i give it 7/10
9/10 for the top one. 7/10 for middle, not liking the 'clone' too much... 6/10 for the bottom, it looks well made, but I just don't really like the 'invert blocks' on it. edit for squishy: 7/10, simple, but smooth.
Well, in my opinion: Top 7/10, Bottom 7/10... But it's probably better than mine. :unsure: OH.. forgot the reason.. We'll I just don't like they colors on them and they seem overly effected(?) I don't know..
