You 100% right for real thing this would be too much saturated. Glad you like cloads it took ages for me couse I am very slow :D

Lovely Mockup! A bit busy maybe - if this were to become a game, I would decrease the background's luminosity and contrast a little, to differentiate sprites and backgrounds better, and make it read easier at a glance.
But as an artwork itself, it's fantastic. Lovely cloud work!

This is awesome.

Thanks.

The UI is so pretty! And the ships too! Such nice lighting that they all look 3D
