Okay.
King of Kings
I liked how the background matched the feel of the render, though ultimately I felt it was too simple - it doesn't appear that you did much but put the background in.
Thorinn
I liked the background, and you blended the render very well, though the tilting threw me off a bit.
Gannon
You did a very good job in making a simple-yet-effective sig; eveything, including the text, just fits together. I feel the render's a bit over-contrasted and too yellow, though, and it's pretty pixelated.
Digi
I love the rain effect. It's awesome. I just think the background is too plain.
Tpt
The transparency is awesome, and I like the color scheme. Ultimately though, I wasn't too keen on the brushing over the render - it just seems oddly out of place. Maybe if you'd done a couple layers, altering colors and blend modes, it would have fit better.
So...overall, I declare Thorinn the FFA winner, with Gannon a very close second.
Congrats to everyone!
