That is looking great!
I think you may have to change your name from 'clueless' as the work you have done show some real skill!!

Just a note on the binding tape issue.
It is worth visiting a local model shop (you have several in Hamburg) and getting some lining tape. There are several makes but the most popular for modellers is made by Tamiya.
It comes in different widths (from about 2mm to 15mm) and is far more flexible than ordinary masking tape and will save you hours.

Looking forward to the next update.

Cheers
