You don't have to current every sig you make. Upload them to an image hosting service such as Imageshack and then display them by using the tags [IMG][/IMG]

Now about the sig:
-Don't use bevel-emboss for the borders. Don't use bevel emboss at all for sigs.
-I'm glad that you attempted to blend your render.
-Once you're finished experimenting with different techniques, look through some multi-coloring tutorials. People don't usually like monotone sigs.

Keep trying. You'll get better.
