My dad gave me this locket (of him and my mom on their wedding day) for my birthday one year. This was after their divorce. I always found it slightly odd that he positioned the photos so that they were looking away from each other.

Your photo works nicely for the 'time' challenge. The composition is strong and I really like the theme you are relating with this photo.
I don't know much about the camera you have, but this photo, as mentioned in earlier comments, would be much stronger if it was larger. I also think that the overexposure on this photo could be a bit damaging overall as well. Personally, I think a darker exposure would somewhat enhance the theme you are working with in this image...
I think, if possible, that it would be better if it was bigger. I would centralize the subject too, as there isn't anything on the background. Just personal preference, though. Nice idea for the challenge.
This fine image would be even better if it were larger. Your lighting and composition are great. If you use Photoshop, you can go to your Image Size... window and adjust the dpi. The max for use here is 640 for your longest edges. You can then use the "Save for Web..." window and fiddle there until you have a jpg image that is under 150 kb. Good luck.
