The maximum size for one side of your photo is 640px, and this is 375px on it's long side. Even the best shot becomes very difficult to see at this small of a size. Looking at this shot now, the branches on the guy's back are very indistinct.
This subject had potential, but the difficult lighting situation has led to blown highlights. The focus seems soft--perhaps a bit more contrast and sharpening would help. The composition is ordinary--I don't think centering the subject helps add dynamic to your image. Because the background is complicated it is difficult for the eye to separate the branches on the man's back--the point is thus lost.
It's hard to see the man's load with the busy background. Color might have worked better here. Also, the image would be easier to see if it were larger.
Awesome reference and depiction! I wonder how many will get this - as they are possibly too young to know about it! LOL..
Nice tones. Wishing for it to be a bit larger... but great idea and execution.
