Please comment on what you think I could do to improve it ect. I was thinking about adding text but I'm not sure as the colours, so input would be apreciated.
Meh, choose a focal point, its not really defined. Sharpen some parts and blur the others. Other wise I think you have a really nice sig, add some text.
I'd go with a horizontal "black-transparent-black" gradient to better define your focal. I'd recommend not blurring the sides.
