Not many modellers do good eyes. Most don't even attempt them and I have seen worse. It may take years to paint eyes well.
The big rock looks to me like a rocky canyon wall. maybe abstract but it gets the idea across.
But the best thing about your diorama is that the idea comes across clearly.
The infantry are all moving in the same direction with one as the obvious leader.
They give the impression of heading towards an unseen objective. If someone can look at your dio and figure out what is happening, you have nailed the most important part.
Good work and hope to see more.
PS. Don't forget how you did that rust, it is excellent and you will use it a lot in the future.
