T-Rs fix does look more or less flawless, so you should go for something like that. Otherwise I think this looks really good. Brushing is great, just keep going, will be a really nice chop, cause the brush is really glossy and nice at the moment
The only semi-toony area I can see is on the c-pillar there... could use a bit more cloud. Other then some really bright highlights it's flawless
Cheers!
