I would also echo a lot of what has been said already.
Some areas could be blended better, such as the skin, whilst some areas are superb, the gore trails and the leg shackle in particular.
For me there was so much going on that a lot of it got lost.
I think it is important to remember that the voters are looking at a lot of miniatures in a short space of time.
If the first impression does not grab them then they may will probably not look closer and therefore miss a lot of the detail.
With so much going on and a lack of a focal point I think this is where you may have lost out.
My entry was "Mr. Magpie says.." and with the images I used I tried to get the overall story across then used smaller images to show specific details. I feel that this enables the viewer to digest the overall piece in smaller 'bites'.
I would also recommend a proper photo setup.
I purchased a portable light box set, including 2 lamps, from ebay for 30 GBP and a camera from ebay that cost 10 GBP. The camera wasn't the latest and greatest but had excellent reviews for macro work which is all that I was interested in.
The results I get now are way better than those I had before.
Good luck on your future efforts.
