i would imagine that the angel is quite an awe-inspiring sight, but i would imagine that the angle you've chosen is quite usual for this subject. for something so well known and famous (or at least here in the UK) you might have chosen something a bit different, like from where the little guy up front is standing. having him in the frame though is interesting for the composition (and gives a wonderful display of scale). also the sky is nicely dramatic, and fits the mood very well. technically it's pretty much flawless...
