A very nice silhouette well composed. The slanting line from bottom left leading you up to the biker is perfect. Sepia effect works. Water in the sunlit area is blown out a bit and the sky doesn't do much for you but makes an effective negative space.
Nice sillouette, but perhaps better if the sky were not blown out. Expose for the sun and sky, if you didn't already do that. Or try to intentionally underexpose and do the adjustments in PS.
