Buildings one: 7.5/10 - I like it, but it's too monotoned and just a bit too bright in the middle. But overall a really nice concept. Island one: 8/10 - Really nice, but the text screwed up the signature imo. One made from scratch: 8.5/10 - Really nice, but the planet or whatever it is looks too out of place and text needs some improvement imo. Big one: 8/10 - Canvas size is too big but otherwise really cool.
firs 8/10 looks nice background/text is good and the animation is nice too and second one another 8/10 its fun to watch
Slayer prk. 8.0/10 8.4/10 i like the style you have on them, just a little small... at least on a 19'' screen
