nice and clean sig. just stick to the simple texts, it would look alot better. also this is just me but i would make it alot skinnier coz the render is long and thin and sig is well sig shaped.
There's nothing I can comment on about this tag really. I like the flow of it, nice a spacey with effects that fill it perfectly. Also I like the lighting and colors. Personally I like the tag and don't see anything you could add or change Nice job.
