Great work! I think this is a solid image and technically well executed. I'm not sure that the person (you?) is adding a ton to the scene and it's what immediately draws your eye. Not necessarily saying removing the person would add to the image, but maybe I'd prefer if he was sitting on the ledge right in front of where he's standing? Woulkd have to see it I suppose. The red jacket would still really pop and make for a strong subject, but wouldn't obscure the waterfall, which is the star of the show. I just think that as-is the pose is a bit plain and very dominating of the scene.

The sky is a bit bland, but I actually don't mind that here. Looks like you did a good job maintaining some detail there in what appears to be pretty flat overcast conditions.

Take all of this with a huge grain of salt, as I'm terrible at incorporating people into my landscapes.
