Yeh I agree with the things that have already been said.
1. The wheels look good.
2. Would change the rear lights to something more subtle and lexusy (never been a fan of the lexus lights...sorry).
3. The front lights look good.
4. For some reason it look in photos 2 & 3 that you have the passenger side skirt on the wrong way round. I am sure its not my eye sight.....might be the way the photo has been taken 
5. Yeh the petrol cap was one bit too far IMO but goes well with the rear lights 
6. Like the front grill.
7. Front windows look a tad dark IMO. Also never been a fan of very dark driver/passenger window tints (plus I thought that was illegal now..!?). Lighter rear tints would be better IMO...less drug dealerish (he hides ready for a flaming). [:#]
Apart from that a nice work in progress fella
