Great color control and shadow enhancements. Text looks cool and serves to tie the render and background with it.

great color scheme and shadow control, and the custom sloth face looks great and is the creativity that drives this site. the fact that the lighting matches the rest of the piece is also welcome.

Love the mixed media. The lighting looks superb and the use of the anime/manga (i don know the difference, but im acknowledging that there is one, so people cant be mad at me) is a very creative and unique approach. Text looks awesome as well. the flares on the text look a little soft though.

Great use of color. I'm not sure what the background was originally, but the blending looks awesome.
