Kenn, I urge you not to leave the forum! I'm one of your fans and delight in seeing what you do. I also urge you to continue posting photos and accept what comes, good or bad, for what it's worth. The critiques I've seen have been specific, non-insulting and valid. But they in no way define the overall scope of your projects.
The thing is, your construction skills are beyond what many of us can do. So it's a given, perhaps unspoken, that your work is superb and fascinating. The critiques have been for areas in which we'd like to see you grow (we all have them). Please don't take them as indictments against your entire effort. Comments are not currency with good ones making you rich and bad ones making you poor. They're just opinions from strangers that count for as much or as little as you let them.
There are a lot of silent viewers, (and I may be one) learning and being inspired by your posts.
