Aesthetic: Not very appealing photo. Somehow toys dont do well on DPC (unless its about "rubber ducky" :))
Technical: Lighting is harsh but the image is well exposed.
Challenge: Not really a fit and maybe thats the reason for not-so-high score. If the theme was "top-lit" or "single source of light", this would have done better.
Conclusion: Overall an average composition. Somehow common subjects dont to very well and to add to it - this was a toy! I did not voted for this challenge but would have given it around 5 which is in-line with final score. The rule is simple - the subject needs to be interesting and if the subject is too common (like the one in your photo), you need to do something really unique with post-processing or capture angle.
Wish you goodluck for future sybmissions!

I was attempting a similar angle.... Allan Wietzallen style... getting hammered though. In this picture though I'm having a hard time trying to pick out the painting as there seems to be a clear shadow from a light source.
