Are these the free demo versions? I hear no round robin or automation in here. I don't use much from Spitfire (although I know they're pretty good), so I'm not super knowledgeable on the particular libraries you used. Also don't forget to have a separate reverb for each patch. You don't want to rely on the built in room reverb. I'd recommend Valhalla reverb or if you have the dough, Cinematic rooms. CR is the best in the business.
