i didn't actually make that arrow in GIMP, it's a vector from another website
for everything else, I made a blue background, made a new brush for the little circles, added a white soft glow to the circles, added a translucent lens flare, made a black-to-transparent radial gradient for the vignette, made a translucent bars pattern for the little blinds effect, threw in the arrow and layered it under all of the effects, and added a shadow.
