Oh good grief I haven't taken art classes in ages, I've gotta go look up non-objectivism! at least not the type art classes that cover theory and art history and that type thing...
It's pretty cool, I rather like it. I like the view, somewhat hidden, wondering what else is there... the use of pattern, etc. The only thing I'd think about is the right side where it gets rather dark and you sort of lose the pattern and contrast and visual interest.
I might have either thought about giving the potted plant back there a bit of a scoot out of the way (if possible) or leave it as is and adjust the vantage point when taking the picture to be able to see the plant with a little more contrast of dark and light (to be able to make it out better). I think subjects/objects either need to be part of the picture/composition or out of the frame (so they aren't visual distractions). Maybe try to dodge out a little more of that area.
Did they have you make a dodging tool yet?? If not I can tell you how (or take a picture of mine I guess... still have it but I use a Dodgette Set I got at a camera swap).
