I like it for sure. I would suggest to add different material for the drilling blades and much more damage sings for the whole drill. Don't forget to share it with animations! :)
Make the the emblems and decorations on the ship a bit less saturated. Why's the canopy so scratched up and not the other parts of the ship that would take significantly more battle damage?
The texture is very noisy, I would remove the noise and instead add more shape-supporting texture elements (edge paint damage, sun bleaching, ground dirt)
Make it fun: Every time you're adding a scratch, imagine the scene in which the shield was being stricken. Also, if the rest of the shield is this damaged, the metal in the middle would be too!

You did a very nice job destroying your scene :p All the textures, little (damage) details, and athmosphere setup make a polished & believable scene. Love it!
Thanks for posting that Surfa. It was a very interesting read. So they basically cull out an area on the model then replace the culled area with a damage model and use decals to cover the seems?
