Mighty Prisoner

This is a protest against animal abuse, but specifically horse abuse. I can't understand how anybody could harm such beautiful, powerful creatures, horses place so much trust in us despite being far bigger and stronger than we are, to abuse this trust is evil.
I am fairly pleased with this considering i almost scrapped it and i think it's my most complicated manip so far, i created the fire circle from 4 stock images which was a first,
i also painted the sky myself, it was an accident at first actually, i was putting some dust around the horses feet and accidentally put a big bit on the sky and i thought it looked pretty good, so moved it around and then painted some stars
also changing from day time to night time was new for me too, and i think it looks fairly convincing
i am really not sure about the fire circle though it doesn't look right, if anyone could give me a hand i'd be very grateful
