At least it's tileable. Now make it orange.

No, really, it's okay as it is. Maybe just these more square green things could be more detailed, since the contrast between colors is too big. I mean it should be more like a gradient, I believe. These tiles can be used as a natural ground, while mine could be used as an inside floor of the temple itself.

Edit: Wait, your image doesn't have Mr. Star in it! How can it be a Space Temple without the space part, represented by Mr. Star?
