The LBP one is my favorite. There are a lot of colors but they are very subtle and blend very well with the overall bronze color scheme of the sig. All of the others are nice too, but I don't care for the second one.
I spy A SPRITE SIG x3. I'll second Ace here, the render sticks out too much in 2. 4, on the other hand, is a beauty.
1st - Not an exciting theme - Not so good text 2nd - A little too monotone IMO. 3rd - Horrible render placement - Good lighting - Add some C4D's 4th - This one's my favorite - Great overall performance - Add some text 5th - Very questionable - Very bad focal - Never do something like this again 6th - It's okay but the render seems a little too far. Make it closer. - Good colors but I do suggest you try yellow. Just a heads up for all you haters out there. This is a thread for feedback and the opinions of other people, so don't get mad if my view of some sigs may be different than that of yours.
RaBBiiTTT, the only problem with sprite signitures is that your image is always going to be small. Resizing sprites always ends badly.
I agree with everything RaBBiiTTT said. I really think that the 3rd and 5th are pretty weak compared to the other sigs, which look really good. The LBP sig is fantastic.
To be honest with you, I find your comment the most helpful and I am in no way offended. The 5th tag was originaly an LP (here). I don't understand why you all like the 4th one. It was one of my first tags and Planet Renders' members did not like it.
