The effects are nice, but everything else just seems a bit off. There isn't really a focal point, the render is so small that it makes it hard to focus on anything. While small renders work in some tags, I don't think this is one of them.
There's also a problem with the lighting, the way you've done it seems to wash out the tag and give everything a fuzzy feeling, making it look really low quality.
Either way it was a good start for your first sig in Photoshop, but it needs a lot of work. Seems like it would greatly benefit from a gradient map or something.
Nice, the lighting is horrible though and my eyes are all over the place. Work on your focal point. Also it doesn't matter if you wanted the text to look like that because it looks terrible and it's hard to read. Try to check out some text tutorials if you can.
