know different monitors show different, but this one is usually very accurate and it shows light blue on the bottom of the "white" background, otherwise nice !
7 - Good shot. Whilst no expert on 'highlight control' re the Challenge, seems to me you have done very well to not 'blow' any surface. Double took on this one, very similar to the other, however the other has more 'light coloring' in it, that and the angle / 'composition' and slightly 'whiter' background got it a touch higher from me. Still a great shot though. Criticism; if possible, different angle/tighter or different crop, just like to see more of the 'light coloring' of the bird(s) against the background. Very difficult I imagine to adjust the contrast here given the colors.
