This photograph has been taken from a very beautiful and interesting angle, capturing the whole depth of the object and not just the front. This does seem a bit plain, and I would have liked some more of the background to show, but did love how you captured some of the tree branch and faded it out as it got further.
The object was captured well, and isn't just smack in the middle as people would usually do. It does look like the rule of thirds was used on this, and even if it wasn't, it is still a good, as I said before, angle.
Very lovely over all, and I liked how you didn't choose an ordinary clock, but one with an adorable owl (which is very cute!).
