What are some design changes you’d make in transformers one?

While I do really like Optimus Primes alt mode in transformers one I think it is a little bit TOO similar to what his earth mode would be. Instead of being a more alien like vehicle it looks like an attempt to mesh the cybertron design and the earth design together. I think making it more like the fall of cybertron design would’ve been a better choice since it abandons any attempt to look like an earth vehicle. What changes would you guys make design easier to the film?
