Hello, Soren,
Welcome to the Aerodrome! I am sure that you will find a great deal of information here, and many forumites who can provide all sorts of help and advice.
Congratulations on a very nice SE5. I have the Wingnut Wings SE5a to build, so I am always interested in how others finish their 5/5a. I notice in your second set of photos that a rigging wire between the left side interplane struts has slackened off a bit: easy to fix! Excellent work with home made decals and painted markings as well. I must also use these methods for my current Junkers J.1.
Best Regards and, again, welcome!
