wow, very beautiful mate. good flow of colors, good blends. 9.5/10 on both. maybe a new choice of renders btw, you were suposed to be able to see his head... give it more 'motion' i guess.
it gets a 6 because the text is ugly? the first one is better then the second btw. nice c4d. could use more then just yellow and they ugly darker yellow. would have to see the render to gauge more on what you did. 8/10
6/10 for top, not much blending, colors contrast way too much 7/10 for bottom, ok color, clear up her face and it will look a lot better, IMO
8/10 for yours, i dont like the text it overlaps with the lighter text behind it ( dont know how else to say it ) makes it kinda hard to read at a glance, other than that it owns
I know, the first one isn't so good, becasue it wasn't origionally meant to be a sig that I would submit...I was just testing out my new lightning brushes (which are sweeeeeeeeeet) and it kinda happened... As for the second one...I cleared up her face a bit, and sorted out the background colours... 8.5/10 --> Love it
