Quality wise this looks fantastic, tho I never was AGT Enterprise fan 

 maybe if they didn't go crazy with those funky fins all over the ship and instead put only that third nacelle and a bad-ass cannon i would like it more 

 nevertheless, great job Wiley  

It was said that the Pegasus tested systems for the Galaxy class, so this would be a more logical ship to test systems for the Sovereign
highly unlikely ;) Pegasus was small scout/science vessel with minimal crew, Galaxy class is luxurious, crew+family faring explorer, dunno about Starfleet R&D but I would not put all those folks in such valuable ship to risk riding ship with experimental / dangerous tech 

 just look at poor Pegasus
