The transparent background isn't completely transparent, I can still see the image block/shape.
It's ever so slightly visible.
Aswell Nero, your borders are blurred a bit too much on the 'transport Ti' one. Aswell the one above it has blurr on the border too.
Prysin, that's cool. Good usage of the overused space art picture. But there's also a bit on the right hand corner with the characters piece (probably glove) but in a triangle shape.
