Good blending, I suggest to add a reflection of the bottom of the robo - crane on the sand. make a copy of the object, Transform - Inverse and give it a gaussian blur. This will add a real look to the image. Good luck!

Fix the links...only #4 is working. Your hi res image is low res.

Your entry made me tear up.

Source 3 is an illustration, and not usable. 5.7. 3D Renders or Illustrations as Source:
Using other people's 3D renders or illustrations (even with permission and no matter in which form they are offered) creates a false impression of your artwork. So 3D renders or illustrations can not be used as sources, unless they are entirely created by yourself. Brushes and clipart can be used, but you need to mention them as a source too.

nice one ,it makes me smile gl author

love the fur coat good luck

Lower shadows under the animals might help in the realism, they look a bit floaty, but that could just be me.. Good luck and fun chop
