You might want to soften the edges of the camel to match the sharpness of the surrounding image.

Also when adding shadows make the 'connection' of the two surfaces similar in darkness. i.e. the camel looks a bit like it's floating because the darkness of the shadow you made doesn't match the parts of the camel that are meant to be in contact.

The shadows are about right in strength, you just need to add that much darkness to the camel as well, or lighten it up where it's darker. If you don't understand what I mean (which wouldn't surprise me because sometimes I don't express myself very well send me a PM so I can illustrate.

PS: Just want to help!

Conflicting light sources/shadows, but a good idea & image. GL author.
