Initial thoughts/My opinion Nice colours and textures of the vase; it's hanging to the right side and the background disturbs a lot
Content/Composition It's a close-up, but that's fine. The main object, the vase is well selected and showing it only partially is a good choice. Also the way you turned it with the orange triangle as the centre works well. If it would be better to see more or less of it at the top and bottom? Don't really know.
It should have been turned CCW also.
Unfortunately there is a second object: the wall paper. While not really sharp it still not just a background and thus the viewers eyes automatically look at it and start searching for .... well, nothing. A homogeneous background, maybe with some gradual variation of brightness would have been better: there is no need for a textured background, texture is already in the vase.
Another issue is the light: you have set it rather flat. My suggestion: play with a desk lamp by moving it around the object and look for the best effect. Especially when you have something with a 3-dim., grooved structure like the vase, the right angle of the light makes it all.
Camera work -technically Focus is OK and you shouldn't have used a narrower DOF here. Of course the background shouldn't be focused too (see above). Exposure is at least 1 EV too dark. Whitebalnce is a little off.
Digital Processing - Technical Nothing that has been done wrong, but you could have made considerable improvements: rotation, increase of saturation to bring out the colours, increasing overall brightness and blurring of the background (would have been allowed this time).
It's not oversharpened but could be more crisp. But that's more a light issue.
Fits the challenge Of course it does. Maybe a slightly closer look might have been better in the eyes of the voters.
Hm, I don't know how big or small this vase is in real life, I am in trouble. :-) I like the roustic texture and the colours against the dark white wall.
Technical: fits the challenge. Looks a bit underexposed. Composition is a little extreme for a vase that doesn't have more flowing lines. With no top or bottom my eye follows the edge of the vase right out of the shot. Focus is good, lighting is flat.
Personal: With as close to the vase is to the background, they're both in relatively sharp focus- I find myself investigating the wall as much as the vase itself. I think moving the vase away from the background and giving it some more dynamic lighting would've helped this shot.
