Don't take my comment to heart, it was not a complaint in fact it is a sort of a compliment, it means I spent time admiring what you have produced and during that time I noticed the corrugated iron which jarred. Perhaps I should have said, 'Nice screenshot but-'
If you post on the forum, you have to expect compliments and negative comments, that's part of the game. It is when you display your hard work and nobody posts. That can hurt.
