Well, my initial reaction is one of sheer amazement!!
You have done an excellent job digitally recreating both the road car, and the now the LM!! WOW!! Thanks so much for sharing - I could never even begin to do something like that at all.
Since you asked - The only things I notice that are technically wrong on the LM are that the right side wheel nuts are actually blue, not red. I can post a photo for reference if you need me to. Also, it appears that you only have that e-brake caliper we went over in the previous thread on the left rear wheel. It's actually found on both rear wheels on all McLarens except the GTRs.
Other than that - and those are both very minor things - I'd call your work a masterpiece.
