I think it's a nice touch that the background objects visibly fade in colour in detail as they recede into the distance. Though I'm curious to know how you created the sky - the dithering looks like it could have taken a very long time to put in place, and then the clouds seem to be almost airbrushed (or the pixel equivalent of airbrushing) over the top of them. Did this picture take a lot of layers to put together?
Here's a link to a psd of an early iteration if you want to check out how I did the backgrounds.drive.google.com/open ...but between the platforms and sky there's six layers
