the one with border

Looks a lot better. The colors are nice too. But the text doesn't really fit in the signature. I'm talking about the font. Try a simple font.

I tried to make some as well.

I don't say they are not good but you use too much of one color in your signature. Also, the text needs work. Try to keep them smooth. The composition in your tags seem fine but your flow needs more work.

The text is the worst part...I just cant make the text match the gfx.And about the color...I like one nice color than many bad looking colors.

Just don't use text in general. It rarely looks good at all.

Work on your depth, lighting and flow. That's mainly what you're lacking in these.
In the first, the background doesn't match the colors on the render.
The symbol shouldn't be covering the focal in the third one.
The focal in the second is too blurry and doesn't stand out too much.

Thx for the suggestions LWafflez

futurekid007: I'd prefer when backgrounds aren't sharp and so attention seeking. It just ruins the whole focal. I'd find that your backgrounds would be nicer if you'd make them smoother and easier for the eye to look at.

Ill try.
