The great thing about this forum is that there are so many modelers here who are all willing to help fellow modelers with advice and techniques. Asking questions is the best way to learn and you benefit greatly from suggestions put forward by other members. You have taken a giant leap into WW1 aircraft modeling by building the WnW kits, even though they are a user friendly kit they still require quite a bit of deft modeling skills and with what you have shown so far you are well on the way to becoming a very capable modeler.
I'm looking forward to seeing you tackle the Fe.2b, but please remember, if there are any aspects of the build that you are a little unsure of just ask and I'm sure you will get plenty of help. Good luck with your build.
