Can you post a pic of the back heels? It is hard to tell from the coloring. The males have a point on the back feet called a tarsal spur and the females do not.
There looks to be a spur but it is still hard to see with the angle of your picture. If you could take a pic of the foot from the back it would be easier to determine. You gave more of a side view. From what I see so far, I say male, but cannot be certain.
