Try making the text an orange glowing color to match the lines in the background, rotating it 40 degrees or so clockwise, and putting it by that little streak in the bottom left corner. That will be some good looking text that doesn't take away the focal, and it will take up some empty space.
This actually looks very nice, especially for a first. I'll give it a 7.5/10, 8.5 if you fix the text.
