the work you do is great! One thing is the sheet steel you are using? Is it zinc annealed? it looks to be. i would suggest using CSA3 cold rolled sheet. It will draw deeper and shrink and stretch much easier than ZA. CSA2 cold rolled is more common but i found it tends to crack easily when worked too much.
I have done quite a few radiator cowls and bodies all using the CSA3 cold rolled. I will never use anything else!
