It's funny but I personally like more the aircraft than the grot or the marine helmet. There's something about the shape of Gretchin that makes it easy for me to figure out where highlights should go. Maybe I'm not excited about it since it was a fast and easy paintjob. It didn't seem that complex or advanced to me. I think you're right about moldlines. I can spot one on the lower right tail fin. The funny thing is that there are many more mold lines I've missed but luckily they're on the underside of the mini and conveniently hidden from view. You're correct about the reference too. It's a WWII Mitsubishi Zero. IMHO it's not such a bad idea...
the grot and marine painting are very good the plane not so its rather avarage
p.s. theres some mold lines on the tail
p.p.s i can geuss the colourscheme- i think it may have been a bad idea (is it a japanesse f-0 ?)
