Well it wasn't a sandwich but more bread and butter. But okay, I don't want this to grow to another discussion about courtesy so I will go into critique-detail - even though this was for fun - because releasing things always ends up in critique (positive or negative)
The stars are just white pixels. They have all the same size and no other detail. You can easily create nice looking starfields by playing around with chroma (b/w) noise-effects (never used GIMP but I'm sure it has those effects, too) or you just type "starsmap" into google picture search. Far nebulae at the right and left borders would increase the quality of the overall image and also stand out the center of the picture where the action is going on (maybe the fighters could fire their laz0rs - so they have a reason to be there).
The joystick doesn't fit into the picture because of its comical look and the blurry edges (some additional erasing needed here end there) . The whole thing only has its right to exist because of the text next to it.
That text has no own theme. Maybe try the ramp of the title (white to soft orange/beige) or give it a more space orientated look ( e.g. a glow or put the joystick in the middle of the text and take a mask tool so the words arrange around it).
The orange bar could be exchanged with a planets atmosphere where the SCP-text is written with a decent dropshadow behind it.
And to point this out: I'm not posting here to insult anybody or show everyone my superior intelligence. I just want to help - and this is NOT for fun - well maybe a little bit
