This white-on-white piece really catches my eye. Your focus is just soft enough to give the whole piece a sort of cloudy feel (very appropriate given your subject). Compositionally, I think you have done a good job of breaking up the monotony of a centered subject by roting it just a bit, so the heads of the angels are nicely staggered.
I think I would like this just a little better if there were slightly more contrast between the angels and your background. Other than that, fantastic!
like the idea of this and the photography, feel that the piece should have been rotated a bit CCW as the front angel is to flat and should be more angular (or is that angeler?....sorry couldn't resist)
