It looks incredible! It's very unique and the theme is great. It's not overdone either. I do see however, that you decided to go with the black door handles and upper hatch handle.
The X5 and 4.6is emblems would look great in Shadowline but you could also just debadge. That would be a clean look. Oh, and perhaps a rear wiper delete.
I haven't a clue what the laws are in HK about tinting but a light to medium tint on the windows would look good. Lower that a little bit and I think your X5 would be complete.
