9/10 Great render choice. I just think the red on parts of the bg are a bit too much in contrast. 10/10 Very nice job on the space theme. -oh nice, I just noticed it was animated, hehe. More points cause I love animation when it's small and good. Perfect sig I say. ps. that car sig with those heads is so funny lol. That's a really cool and funny change from the normal heads.
The first one is pretty good I like that one a lot. The second one a bit to blurry and light because of the brushes. For the 3rd its alright.
7.5/10 The background is pretty good, but I don't really like the render or the text, and I don't see a border.
