1st and 5th are the best. They actually give off a sense of depth, and they show off the focal. Just learn some new effects. ^^

Not bad. Looks pretty abstract. ^^Just sharpen/blur some bits to create depth and a focal. Then reduce the size of the text, to about 9-11px in size. Then make a new layer, right above the text, and go to Image, then Apply Image. Click Okay, then right click on the new layer and select 'Create Clipping Mask'. Click on the Move tool (keyboard shortcut 'v') and click and drag around until the text gives off a nice effect.

For the first one, here's a quick tip. Never, EVER, duplicate the same render, or use more than 1 figure render, (two people), unless you know how to execute it perfectly. Remove the scanlines from the first's focal (face), and blend the render into the background. (smudging is an easy effect, and looks good)When using Cinema 4D renders, don't just set them in there. You have to manipulate them to look nice. They are commonly used to create depth and flow to an image.For the second one.. this one is way better. Just simple stuff from here. Place the c4d over the render of Venom, then smudge venom's lower half, and add some lighting.

Here's the thing. With forum signatures, you want to easily see the focal (usually the face or main part of a render / stock), along with a nice background, effects, depth, flow, and composition. What you're doing here is sticking some renders on and not bothering with blending and proper effects.A good signature size is 380x120 pixels. That gives enough room to play around with.All in all, it's not the best, but it's not the worst. Just read up on some tutorials at some places. (but remember, don't follow a tutorial exactly, experiment to see what you like best!)
