^ I think the last two signatures aren't included with the showcase because it's his current signatures.

1. Good render, although the background doesn't really match with it. No blending whatsoever, and it seems like you merely made a background, and pasted the render. That's fine sometimes.. but the background doesn't make the signature good in any way, in my opinion. Also the text doesn't suit the signature at all. It's barely readable, the long quote you placed.

2. I like the render. It's one one of those renders that make a really awesome signature, in my opinion. Your background, however, is too plain. Very plain. o.o" I get the 'go deeper into the world of light and darkness' thing, since it seems like it's what you want to depic on your signature. But like I said, it's too simple. >.<;; You also shouldn't have placed that red render on the lower right.. and.. again, work with the text.

3. Not the best quality of render, but it could work. The signature lacks blending, no lighting, and no depth. _-" And.. as I mentioned in my previous comments, the text. It would've been better if you used much simpler ones like Arial or Verdana.

4. It's too huge to be a signature. Crappy render (no offense). The background is also too colorful that it destroys the signature already. And when you left a black space on the center, the colored border made the signature looked like a frame. o.o" Much simpler backgrounds would work for it, I think.

Good job, though. Practice makes perfect. ; )
