1) you are not your customer - just because you can't conceive it on your own walls doesn't mean that people won't/dont want it.
2) houses in the US are big, by many UK accounts they are gaudy monstrosities, but I have clients with 24' ceiling heights
3) there seems to be a notion that I come across regularly that a thing should never be shown bigger than life - this is absolute hogwash and based on nothing useful. a beautiful potrtrait where one can see all the pattern of a loved one's eyes has meaning to some people
4) as mentioned in another reply, paintings of this nature exist all over the place and anyone of status used to commission such a painting. these are loved, and also status
5) art to one person may not be art to another, that's ok. some people pay millions of dollars for a rather lousy reproduction of a campbel's soup can label....or a little girl and a balloon that becomes confetti, or (god forbid) any of the garbage that richard price pedals.
There's no need to get quite so defensive, old chap: I was expressing incredulity, not disdain.
1. Obviously. My lack of conception extended further than my own walls, but that doesn't really matter.
2. Oh; again, I made no comment on aesthetics.
3. The notion may exist; but I made no such comment. It would rule out photomicrography as art, for a start, and I don't.
4. Yes, large paintings exist in English country houses and castles. I'd be very surprised if the number painted in the last hundred years reached triple figures. The operative words are "used to".
5. Again, you seem to imagine that I was denigrating your work. Far from it: if the niche exists and you can fill it (and, given that you're contemplating spending a lot of money, I accept that it does), the very best of luck to you. Clearly the fact that I find it hard to imagine represents a deficiency on my part. I remain, however, convinced that in the UK, you'd be on the dole pretty quickly.
