Sig.

[Newt]

This is my second sig. tell me what you think

[Virtue]

For a second sig it's not too bad. The main thing I would do is make the render of yoda stand out more. Try not putting the background color over him and blending him in a little more. To blend, just smudge a bit all the way along its edge and then duplicate it and gaussian blur the bottom layer just a bit. Also, a little more variety in color would make it much better. Those are just a few tips, but again, that's pretty darn good for a second sig! Keep working and experimenting!

[Newt]

Which one of these sigs do you think is better?

[Dark Method]

Second one. The saber looks kinda funny in the top one. Maybe it's just too bright?

You've definitley improved fast. My first few sigs, were, filter,render clouds, slap a render in, add some ugly text and call it a day. Well..sometimes I still do that, heh.
Keep at it.
