Did you use a cable release or self timer? The piece looks sharp in places but not overall. That makes me wonder if you lens was clean or if there was very slight camera movement from pushing the shutter button with your finger. Some of the image looks fuzzier than others and it doesn't look like depth of field. It's also a little low in contrast which also suggests a dirty lens or filter.
On my computer the color doesn't look bad but then I don't know what the true color is.
