The art style of each element clashed, I couldn't look at the screenshots without hurting my eyes.

The space backgrounds look like photos. The rest seems to be pixel art.  

You could make the space backgrounds out of pixel art instead (black with an occasional pixel planet or pixel)  to match the rest of the style.  Your planet backgrounds also have a lot going on compared to the water and grass (blue and green screenshot) that have very little background "noise".  They don't appear to be from the same game.
