- image has so much noise, I doubt that it'll be accepted even in the less pretentious among the low earner agencies
- it is also shaken, that's why is blurry
- white balance is slightly off
- also, piece of advice: shoot and work in sRGB, not adobe rgb
- other piece of advice: resize images to the smalles possible, when uploading your first 3.
Here's my take on your image, this is how I would have submitted it. No noise, sharper, but you can still see that camera was shaken:
http://bit.ly/rlBQkCquick 2 minutes work - remove noise (no plugin), resize, correct white balance, sharpen iguana's face. It's not perfect and saved at 70% quality, just to give you the idea.
I'll remove it after you look at it.
I'll also re-shoot this image.
