Millenium wing exterior of the National Gallery in Dublin, Ireland

I like to hear your opinions about this picture. I really like it,

but there is something which doesn't make it perfect but I can't find

what that is....

I have been to visit the building and I know it is a tough site to take pictures at. It is quite constrained and angles are not very forgiving. Picture is not bad esthetically, but it could have been composed a bit better.

I am always more attracted to architectural photos concentrating on one well executed detail of a building, than building as a whole in it's landscape. That building has a lot of excellent details. I think you could have captured them a bit better and shown us the architect's intentions in doing so.
