Love it man, KIU, and great band . Could be better, the background is really bland and the signature is in need of a light source, maybe add some more interest as well, the mesh c4d has nice flow with the signature though. The render looks really LQ, and you could use a light source, also the effects are really busy, need some flow in there, keep experimenting around and stuff though you'll get better.
Not to bad for your starting signatures, at this point I can really say is just look at tutorials to get familiar with the program, other than that, ask people for questions and stuff.
Much better, keep it up, and I like the version without the border. When did we skip you? And not a fan of the colours, looks like you inverted it from your previous signature and sharpened it a bit, try more styles. Looks good, nice work, but maybe make that glow off the center more of a softer colour instead of blue, nice work though. Render needs some sharpening, add a lightsource, and some more depth.
Looks great, a bit monotone but I like it that way, maybe make it a bit more vibrant on the apple, other than that nice work.
Looks nice, but I hate the text, nice effects though, but maybe tone it down a bit on the right side. Really plain in my opinion, work on more effects, and your text is meh, also he looks a bit clouded in effects on this one so it looks flat, go for depth as well, decent lighting. Lower the exposure of light on his face and hands, and change colour of the text, also add some depth.
its bland...and the smudging you did on his body and arm looks weird. The bg is a little bright and throws off the sig, IMO. You've done better, the text could use some work, try moving it closer to the person and make it more solid, that looks a little blurry.
