I think these are so close to being perfect, but the fronts are really not working at all for my taste. The rears are great, except for the angle of the back portion. These seem to be trying to capture the essence of a Liberty Walk flare set, but in execution they miss the mark for me. If you look at what LB is doing, they are accentuating existing body lines and creases with the angles.
Liberty Walk Aventador:
This set is visually jumping through a lot of hoops to do something similar, but in a way that misses the point a bit. The front flares in particular are just not coming together; the problem is the rising line that comes up to join back to the existing character line. I really do think you'd be better off with no rocker portion at all (as some have suggested) if you're going to do that, or making the lower rocker portion fare in like the ABR S130 flares and having this require some cutting to install (or make it a full fender replacement).
ABR S130 flares:
I think for the price y'all are charging, these are a great starting point, and even with these criticisms, I'd probably still be seriously considering a set if I had a Z in my garage. I spent a few minutes in photoshop with a random car I pulled off the internet to visualize what I think would improve these if they make it to a Version II. Looking at how Liberty Walk treats cars that don't have dramatic body lines at the mid-line (GTR, M3), I just brought the front flares all the way down to the rocker. On the rears, I made sure that the crease line where they terminate aligns with the existing character line, and that the trailing edge follows the bodyline of the car. I think mine have too many rivets, and now that I look at it, I think it would be cool to have a small cladding piece at the bottom of the door to tie in that portion of the rocker line as well, but I don't have time to work that out just now.
Here is the LB Works GTR to show how they did their front fenders:
