You know what's awesome? The first TF custom I saw from you, IMO, needed alot of improvement. I have actually sat and watched as your customs have gotten better and better, and its only been roughly a year.
(I haven't painted jack yet, so feel free to ignore my criticisms)
The only thing I think needs any improvement here are his shoulders, they could be refined a tiny bit. But its otherwise perfection, and Chromedome is, IMO, your best custom to date. Hats off to you, and Primus help us if you keep getting better at this rate.
