beautiful work..but just a thought ur window is burning its heavily exposed..try reducing the exterior light & put a filler light of bout a 0.2 or 0.3 to illuminate from inside..it should also cut ur render time drastically... just a thought..& also if u using an hdri image there is no reflection of it in any details..nor is it seen as a background in the exterior...so thereis nothing to match the lighting to...actually an hdri file is used for either an exterior scene to match the same image as in hdr or an interior with a view of the bg through the window or a reflection on the glass or something..to give a reference image....but overall an lovely concept rendering...
