Your out of focus model is the primary technical issue with this image. And though you used a toy in a portrait challenge that shouldnt doom you to a low score. But you would have to present Kermit in a more artistic or creative way. The straight on shot with really no background or creative composition is going to prevent you from garnering the higher votes. I have been quite successful with this same model and the voters can be forgiving, but you really have to nail both the technical aspects of the image along with having shown some creativity in the setup. Hope this helps a bit.
you probably should have used the sharpen tool after resizing. i've discovered that it has a huge impact on the quality of the picture. it may not sway DPC votes by much, but it at least helps your image. hope that helps some. :)
It is out of focus (and since it's not a living person, you should have enough time to get it in focus) and a portrait of a non-human doesn't score too well (I know!)
Cute and fuzzy (both subject and focus). Was this a humorous entry? I hope so, because the score is probably taking a major hit. Good luck, and have fun!
