I like this piece, but the perspective is a bit off (take a close look at where all the tops of the buildings go off to different points on the horizon). Also, the sunbeams look artificial and in fact wouldn't be seen outside on a bright sunny day. One would normally see them where sunlight breaks thru clouds or a window and there is a relatively dark background to view them against.
I do like the pen and watercolour wash feel to this, though.
Hope you don't mind the crit's. I never know if this is what people are looking for here.
