I like the stump sculptures shown by JD and TeePee, I just don't like painting on and messing about with trees that are growing in woodland. I'd have less of a problem if the odd tree in a park or garden was done like this but for me....I like my woodland as it is.
And yes, I fell live and perfectly health trees all the time....sometimes for good reasons imho and sometimes most definitely not (clients wanting trees felled because they can't be bothered clearing up the leaves once a year!!!!!).
I think there's also a difference with harvesting wood to use (furniture, building etc) like you would harvest wheat to eat and painting trees or....for that matter wondering into a field and painting all the wheat pink....coz it looks nice!
Just my thoughts, wouldn't want to fall out over it lol
