I really love this one. Monochrome subjects with just a splash of color isn't something I see very often! And although I'm not a black and white person usually, this is just too good to pass up.
Everything is top knotch here; the toning and shades of his muscles, the way he sort of arches his back outwards, his grip on the escrima sticks... But the thing that catches my eye most is his expression. It's one of those looks that practically scream "Bruce Lee". It makes me want to go watch Enter the Dragon again right now!
Overall, I cannot find something to nitpick at here, especially since it's all way better than I am capable of doing. The anatomy is great, the lighting is great, the expression is great, and the splash of red in the background adds a nice touch of life to it.
