|Greetings from the Critique Club!
Hey Liz, welcome to DPC :)
I gave this image a 4 during voting, and, um... This is embarrassing. I marked it down by at least a point for bad spelling. And now I looked up 'vane' in a dictionary, and, ah, um, I see... I'm sorry!!! Probably would've been a 6 had I looked at it for a bit longer, and had I known what a weather vane is... lol I apologise.
As for the image - good focus, very nice and simple. The reflection is really good, and the subject is interesting. And the composition is great - very nice use of the rule of thirds!
Postprocesssing-wise, I think you've done a really good job. One thing I'd recommend playing with (just in general, as well as for this image) are soft light layers - if you use a low opacity soft brush, you can gently paint on all sorts of bits of light and shadow, it tends to make light in photos more interesting.
Anyway, great score for your first challenge! And I look forward to seeing what else you submit :)
