Greetings from the Critique Club.
I look at this photo and see a lot of potential. It to me is already a very good photo. But what if you had been able to get in closer and framed only one of the smaller branches and needles. I think the photo may have been more dramatic and wouldn't lose a connection to rhythm. Do you have pine cones to go along with this tree or is it some other tree? Maybe a macro of the surface of the pine cone. There's a lot of rhythm there. I'm not saying you didn't meet the challenge I'm just giving you alternatives on what i think may have been available for you to photograph. I like the framing and the fact you went with a silhouette. That is a nice blue with the clouds giving it a pleasent touch. Again, you have a good photo here that may or not have been better if you had gotten in a little closer. I hope this helps some. I've been having great difficulty writting these lately. Feel free to e-mail me if you have questions. Good luck in future challenges.
I'm not really sure if this is an example of rhythm, but I'm not docking for it. Something about this shot seems missing or off to me, but I can't really put my finger on it. I think the crop is just too tight for my tastes. 5
