Try to adjust the color to your source pic.

This can be done by selecting a part of the stone pedestal, make it a new layer and select the guy layer then go Image- Adjusments - Match colour and select the stone pedestal layer.
For realismyou need to put a shadow from the cage on his pants and place soem shadows/highlights. Pay attention to the shadows in the background when you make this.
EDIT: in case you're new around here, i should tell you that you can edit your entries (before the contest closes) by going to My stuff-My contest Entries, and uploading the new & improved image.

But as i can see , if no one else enters, you'll win the 3rd place, lol!

I think you did a nice job, I think the statue or "Puppet" looks to big, in proportion to the bottom part. Still I wish you good luck.
