I don't think we're here to validate philosophical beliefs about what consists of 'indoors' and 'outdoors'. Both of those tags are used to refer to whether subjects are inside an enclosed building or out in the open air. No more, no less.
As for "good art", I don't think you can necessarily stick the 'realism' label on it -- sounds a bit misleading. Can't say I understand much about what you're saying though. :x
And I suppose Wypatroszony now might know why this user arduously tags text on everything.
In any case, this is going a little off topic.
