Go for it, Matt! At the very least it brightens up what can be quite a dull jacket. Flight jacket art is a fascinating subject, you can either faithfully copy an original design or make up something generic - whatever takes your fancy.
If you study period jackets and WW2 era pin-up art, you'll soon get an eye for 'period' faces and poses - there are plenty of modern examples which really don't look quite right.
May I suggest that you do the appropriate research if copying an original, so that you will be able to answer the inevitable torrent of qusetions you'll receive from curious people whenever you wear it :laugh:
