A size of 360x270px makes this one hard to view and critique. My first impression from this little pic is that it is quite dark. It might be missing detail in the shadow parts just BECAUSE you are presenting us such a tiny photo only, but at the same time it might be missing all together?
And I am not sure I find the view you chose to photograph all that interesting. Lots of "empty space" covered by the back of that seat on the left, very "condensed" lines of the poles to hold onto, while - had you moved only a tad more to your right - you could have worked with them as a nice element of repetition, feet (?) on the right that aren't attached to anyone, but only reach into your frame ... sorry. All in all this doesn't work for me that much.
