Its amazing to me that a film camera produced in the 70's still commands hundreds of dollars -- at least on ebay. The versions I've been looking at with the DP-12 finder cannot be had for less than $200, often $300. Talk about holding value.
Yea, you've got several problems, actually
1) the lighting, as mentioned before, is weak
2) you need to put more thought into the composition. Your background includes a chair and other cookies in various stages of being cut off.
3) the texture on the table is a bit distracting
Hope that helps...
