I like this a lot Great concept The first one is the best It looks like it's cut off though, where the green starts, the yellow bolt makes it look cut off from the rest of it, you should try making it flow more
nice colors. the lighting on one seems a bit screwey at some points but still very kewl nice concept and c4d
I like it, but I would remove that right side where it is a bit darker. First version is really nice.
