One of my favorite birds Mark and you did a nice job with the focus, exposure and the composition. although it could be a little higher in the frame.. I would like to have see this at more of an eye level rather than photographing up but that is sometimes not possible. Beautiful blue sky too. Thanks for sharing !
I've photographed lilac breasted rollers many times, and never get over what a beautiful and fantastically colored bird they are.
This is a really nice capture, but I would suggest lightening the whole image by about 2/3 of a stop.
