vignettes too much man, turn that opacity wayyyy down.
shots #2 and the last are the best, getting tight on shots is cool, but on most your giving no context on where the skier is at, they are just floating, on the two shots I mentioned you have less clouds near the bottom of the frame giving a sense of place. Also I think you need to get a flash, help them pop out of that murky background.
no context. confusing pictures. dont know where they took off from. use better composition. clearly get better angles. dont use the vig or if u do keep it real low. it should never be a distraction as huge as the ones in the pics. happy.
i cant ski. i just film and take artsy pics with an expensive flash i dont know how to use. dont hate.
I agree, the vig is a little much and as everybody else said, context. Make the shot not only about the skier, but the environment too, and shoot it in a way where they work together to form a good image.
