Here's a final design. At this point it's half-decent and I'm happy with it myself. I ultimately exaggerated the ZTK Package features applying them to such a small form, but I think it looks aggressive enough despite not being truly realistic. I also made a quick top-down convertible model without the ZTK package just for fun. A little bummed that I de-Technic-ified the rear-end so much but looking forward to purchasing the set soon and seeing how the modifications play out in person.
