Finally found the solution!
I googled and found some great stars and sparkles brush, and filled the void with it. Now it's all shiny and sparkling and full of glory!

1280x1024:

1366x768:

1600x1200:

the 1600x1200 is a bit different (mainly in the face positions, but the 1366x768's is too, so I guess it's not that much of a difference) because the resolution is bigger, and the images need to be... well... bigger, so that the pics are clearly visible. As such, I can't really do much for different customizations. At first I thought I have more space due to bigger resolution, turns out after you make the images bigger, the proportion is pretty much the same

The only thing upscaled is that cover collage, the face orbs that mine has are actually downscaled from the original resolution
With this, I'll close the poll, and remove that awesomely huge pic in my last post, it's troubling my view of the forum board
