I prefer to work in a more painterly manner when doing these profiles. Working this way can tend to get out of hand a little, but I prefer to put anything new on a separate layer no matter its size as it makes it easier to manipulate later, this can as was the case of the Thunderbolt that I posted earlier lead to having 400+ layers, but with a good work flow it becomes easier, I use a layer mask on each layer and organise layers into different folders for each part of the profile eg wing, fuse etc.
Im not sure how you guys do it, but it seems to work ok for me.
Getting bare metal to look right is the ultimate challenge for me, you seem to have a good understanding Jester, but I do enjoy a challenge, maybe if I ever finish the spitfire.
I have tightened up the panel lines as suggested and it does work a lot better.
will post a update when I get my Broadband back on-line.
cheers
