The mini does not seem too bad. The blue cloth really does not go with all the earth tones of the rest of the mini.
Your lighting rig is lacking, the base is underlight and looks muddy or over washed because of it.
Overall, your light is too harsh or you need to invest in some dulcoat as there is a shine on the mini that is distracting.
Finally, some competitions want the mini to be front/back and the photos to be side by side. Here, the limit is the number of megs and the width of pixels, it can be as tall as you want. Try widening the pic and stacking the two views vertical to give us more details to view/vote on.
And it would not have been inappropriate to have started a new thread for your review but highjacking threads is a fine art around here so you are already fitting in fine.
My overall first impression of this mini is a 6. Not bad, but you will do better as you learn.
