I've added some nice bevels here and there, a nice piece I've forgot and created the missile. I can now say the modelisation is complete, if I put more work on this model, it will be on unwrapping, rigging and texturing. (Probably in this order too)

Anyway, I hope you enjoy this model and have a great day!
