First of all congratulations on almost reaching your 5.8 target Magen :o) Setting goals for your shots each challenge is a cool idea :o)
Composition:
My initial thought was this was a stack of funny coloured cookies! I really like your choice of angle here, I am not sure about the red 'object' in the background but it does help that you have it out of focus otherwise I feel it would be quite distracting.
Technicals:
I have to agree with your commenters that a slightly deeper DOF would have helped this image, not a lot though just enough to maybe have more focus on the middle 4 or 5 'cookies' ;o)For me this is the main reason why voters may have given you a few less points. You have captured some great detail and textures and I actually feeling the lighting you have used helps highlight the different colours :o)
