I see you never received the critique you requested so here goes.
Does this suck? Welllllllll, not if you compare it to my first couple of challenge entries, LOL! Mine really sucked, oh wait, they still do, LOL!
Anyway, this has potential and could be salvaged if done a little differently. One of the things I learned during my time here is to be totally aware of what you are seeing through your camera. You saw the peanut butter and bifocals. I see those as well, but also the pillow, the red edging, the heart or flower or whatever else that is under the pb.
Now, take the pB and bifocals and put them on a plain background, all white, all black, all any solid color and see what a difference this can make just doing that. All the distractions are gone so now you can concentrate on your subjects. Next, the arrangement. Fool around with it, try different things, glasses on top, pb wearing them, top off the pb, glasses inside, you could do just about anything. And then try different angles. From above, the left, the right, below, head on. See what you like the best. The one thing I love most about digital is that I can take 100 shots learning and if one comes out right and I remember what I did in that one shot it's worth it. If I get more, great!
Next, your lighting. It's a bit flat and dull. This can be corrected in post processing either with levels, brightness/contrast or curves depending on the program you use. If you can get it right the first time that's even better but if you have to do a little correction on post processing, no big deal either, unless of course your flash doesn't go off and you missed the perfect shot and it's pitch black, LOL :)
Last, composition. I don't this this is bad overall, I like the use of space in this shot and if it wasn't for the distractions it would be pretty good over all!
I see you've only done 4 challenges and haven't faired to well yet, hang in there, you get better with each one, sometimes you slide but you do learn.
I hope my comments help and Good Luck in future Challenges!
