Very good elements, the tone is right for what's happening. I only notice something odd about the mountain, as if it has low opacity at the top, but very good work.
It's an excellent piece, with good lighting and great sculptural skill. However, I notice that some parts are very detailed while others lack that detail, but I understand this due to time constraints.
The weapon, its components, and ammunition are well captured; excellent work. You just need to keep practicing to further refine your models, as you already have a good grasp of the weapon's proportions.
The idea you wanted to convey is well done, and the speed effect you created with the stars is great. The only feedback I could give you, or that I would have liked to see, is a more complete grayscale, since it's only black and white and I feel like some elements are lost.
