Very nice composition... maybe a bit over processed? There is a halo around the figure... and some noise... but, it can be improved with a little bit of work.
I like the idea, and the action of the catch. However there are a couple flaws that I am sure will cost you dearly in your score. First of all - a lot of sensor dust! While unfortunately basic editing does not allow for clean up of this, cleaning your sensor before the shot can prevent it. A simple test shot at a clear blue sky every day or two can be beneficial as to when you need to clean. Next, the image looks like the focus was quite a bit off, and you tried to recover it by sharpening. there is only so much sharpening can do though - thus the halo effect around the fisherman. The composition is strong, and the action of the rod I like. I hope my comment is found to be helpful to you.
Good luck in future challenges.
