If I might add one critique to your skin, and naturally everyone may do the same to me, I have seen a lot of images of real 109s, specifically researching some skins and some paint schemes for a few models I've built, and never once have I come across any that had bolts at the point the slats connected to the spring arms. I have noticed it in your skins, and it irks me (in a minor way).
Mind you I still respect your skinning abilities and this is nit-picking, but it is a nit and I must pick at it.
