Good toning here, which is a fine start to this challenge. You haven't gone for the blatantly gooey sepia, but something a little harder, a little less blatantly warm, which is effective. my problems with this image lie, as a couple of people mentioned in comments, with the lighting and composition.
The direct on-camera flash has left you with some very very harsh light to deal with - the very bright near bed-post, the brightness of the wall, the very ugly shadows of the near bed-head too. Coupled with the brightness thing, your placing of that near post in frame makes it arguably the strongest element of the photograph, the thing the eye is first drawn to: but the flat light from the flash allows no shading of that object to give it any sense of depth and thus kills any interest it might hold for the eye. Compositionally, that post also obscures what one might think would be the 'natural' point of interest in the shot - the head of the bed - and that makes for an uncomfortable picture. Detail and difinition are fine, but it's you lighting that you most need to work on on this evidence. A good first rule is always to light from the side - get a remote flash, get a tripod and use natural light, but direct on-camera flash will always produce that flattening effect, and is rarely useful - especially in still life photography.
