New Alla Prima Space Painting

Alla Prima Space Painting. Fix?

So this the first real project since moving. Alla Prima, meaning the work was done in one sitting, was the technique used with acrylics. It was first intended to be for a special project in a desert landscape, but is now slated for inclusion in my Space series. It is intended to convey a sense of strangeness, excitement and give a nod to the space craft used by cartoon makers of the likes of Tex Avery. However, at this point, it feels like it needs some fixing. I can't put my finger on it, but I think am leaning towards darkening the space rocket, adding some reflections and highlights on it and perhaps lightening the alien terrain behind it. As far as Alla Prima space paintings go, it turned out ok for my first time. If you are actually reading this, feel free to comment and leave your suggestions. Thanks, as always.
