Certainly a neat concept, love the overall simplistic look. The text seems to be alright, but I don't like how it overlaps the lines. Maybe if you scootch it over towards the left a bit more.
I also think the large empty blue areas could be given some more detail with a soft round brush at 94% opacity and the brush setting set to scatter, just a little bit of scatter. Or just just straight smudge lines, I see some dark blue and a sort of aqua color in the empty blue spaces, maybe just smudge those a bit to make it more interesting.
The red also seems to be having a bit of trouble blending into the white lines.
Great work.
