First attempt at Gundam00 Exia

This is my second project using 3D modeling software, and so far I think it is coming out fairly well.

If anyone could give me some suggestions on how to model more efficiently I would greatly appreciate it. I feel like making all of the pieces separately isn’t the most effective use of my time. If anyone would be willing to teach me, or show me to a place where I may be taught, I would greatly appreciate it.
