this was for a request on another site but i dont like it at all :/ and the text is very bad, and after uploading this to the internet it looks alot worse than bfore
also i notice more looking at the render uplclose it may have been to dark :/ and fuzzy :/
(was obsiously attempting to use earlier tut :/ for help)
your stuff is not bad at all. Your last one shows improvement. Just some advice, on your 2nd one the text is hard to read against that background. Just try and be aware of those things when making sigs. I find text 'style' and placement can be one of the most difficult tasks in pulling off a great sig. I have had trouble with that in the past before too. 😛
I like to use 'dropshadow' or 'outerglow' to try and make the text stand out. Of course there are other ways, but those are the two I prefer. 🙂
