@gubhart Awesome! That's a lot clearer. I would look at making the leg and arm position on the cow just a bit stronger for a clearer silhouette read. There's a lot of negative space in the sky so maybe flip the spaceship so the smoke drifts across the sky a bit, and enlarge the cow a bit more so her really hits that Rule of Thirds golden spot and also takes up a good portion of the composition.
Finally, I'd push that horizon line curve even more and lower the mountains in the background to really emphasize the distance and vastness of the space!

That's my braindump of ideas!
