Thank you so much for the best feedback so far!
Yes every part is built by hand and btw did you get the new version from youtube or the older one from here? I added a bit more variation etc... and I'm also going to add more in the future of course.
And yes that's the point about the roof which nobody ever figured out, but I'm really glad that somebody at least realised how to use it :))
After all, the "enjoyable moments" you just mentioned means a lot to me and thanks again for your kindness beside the honesty!! I am still working on it.
