it's just colouring in isn't it?
I know you are not being entirely serious but.....
......you could well argue that some of the profiles I've done, I've just traced around the original drawing but it's a little more involved than that. Hopefully I've demonstrated that with more esoteric subjects such as this, it does require a little creativity. As for the "colouring in", often, just choosing a colour scheme can be an art form unto itself given the options available (never realised how much I like orange until I started doing these).
To the naysayers, I would argue that presumably the Mona Lisa was just coloured in at some point. Was going to the moon just playing with some pretty big fizzy drinks bottles? I am perhaps belabouring the point a little now!
Anyway, the profile.....
Some tweaks and a little bit of highlighting and weathering (must resist temptation to weather new aircraft!!!). Next up shadows and finishing touches.
