Hi Ken,
looks good, which squadron are you portraying?
R.e. Mini-wings, you do sometimes see them being worn on the right breast, even with the Polish wing. However it isn't all that common, so not wearing them isn't a problem what so ever.
Have around 400 photos of Polish Air Force members, so feel free to get in touch and I'll put them onto CD for you.
All the best,
Pip
