nice effects but the text needs work
Definitely work on the text, it's too blocky for a sig like this.
Try and work on the flow of your effects, there are a lot of those sharp and jagged edges that could be smooth curves.
Colours are great, nice work.
Needs work on the text and effects as ptka said, they're too sharp to fit in.
