Mechanical Logo Animation

I’ve been working on this project for a few weeks now and I’m looking for feedback on how I can improve it further. I’m not happy with the logo material (I don’t really think it fits with the rest of the scene) so I’m open to suggestions. Any feedback on anything you think can improve is much appreciated.

It’s super anticlimactic. The logo finally sits into place and it instantly cuts to black. I suggest leaving it visible and perhaps having a gleam with a very powerful mechanical energy sound after a brief two seconds would go a long way.
I’m a fan of the materials and the like, I think they look nice. I don’t have any idea what the logo is about though.
