Hi Guys.
I've added a few more details. I feel like I am eating an elephant. I have now identified no fewer than 6 variations of side doors on these birds. Doors and side windows are now attached, as are a bunch of the aerials. Still to go is the interior, cabin windows, jetpipe, weathering and glossing and revise the overall shape shading and then I think I'll call it quits on this one.
Yellows and oranges are a pain to shade. One tip I found (by Caruana I think) was to shade most colours towards black but orange/yellow towards red (reddish grey, or greyish red, or something).
I make a selection where the yellow is, and turn up the red level in the RGB thingie 1/4 of the way up. (What I just wrote is probably hopelessly unclear, but I hope not . if that is the case, just shout and I'll detail)
Your Huey is very good though, but the shading does look a bit dirty.
Thanks, Gamary.
I have been toying with the idea. I might see what I can do with adjustment layers so I am not upsetting the shading for other schemes.
