Arnie,
Everyone to their own. I can understand your views, but at the same time it is always nice to have some full canopy trees in your collection. Once they are at this stage, there is not much "artistic" talent in keeping them this way, which is maybe your point. It's getting them to this stage and keeping them healthy which is the challenge.
This is very nice tree.
Not much to do with it really. The shape is a little taller than a traditional broom, so is perhaps more naturalistic looking. The pot is a great compliment in a nice soft tone and is spot on in my mind with regard to size and depth. The only thing that spoils the whole composition (and this is being VERY picky from a potters view point) the "feet" glare out at you. If these were oxided (or even painted now

) then they would just dissapear.
Great Photography, and a tree I would have in my collection. ( I have two as it is ) !
Ian.
