Great work, it's been a pleasure (and a privilege) to watch the creative process on this pit, I go through much the same process when designing art work for decals and profiles, always two steps forward and then one step back (by the way if you need any graphical work done I'd be glad the lend my Illustrator skills when needed).
Its probably too late but do you have copies of:
Monogram Close Up numbers 14 & 15 Japanese Cockpit Interiors (Parts 1 &2). These can usually be found on either ABE Books or eBay from time to time, sadly I have every other Close Up except for these and Close Up number 19 - Kikka
