Hey Tim... looking good! Glad ya signed up!
As you probably know, I don't get to this end of the forums too often. Eventually I will be sliding on over here for the expertise of this fine group when I start building a 1/24 Fujimi Datsun SR311 to replicate the race car that my father-in-law drove. But that's another story!
You're in the right hands in these forums... everyone is very helpful!
As Bob mentioned, a wash will do that thing some good. The great thing about this project is that you can't screw it up. In my opinion, a very heavy wash of black followed up by another of, say, raw sienna will make it look grimy, dirty and nasty and that's the look you want. (I think )
I anyone has more input... let it fly! This kid is very talented and catches on very quickly!
Don't be afraid to ask questions here or at the "office". (You know I'll drop anything for a modelling related question!)
P.S. - I'll be keeping an eye on you! CONTACT!
