Where's the Sling Shot? hehehe.. inventive (need to fix the wing tip on the profile bird (NITPICK) ) good job and good luck

The birds need to be slightly repositioned on the rings, their feet are too far in front, making them look pasted in front of, rather than on the rings. Also, the "sparkle" brush highlights are bit too obvious, reducing the opacity slightly will make them seem more natural.

Nicely done. Add some shadows where the birds sit on the rings, Agree with Mossy on the sparkly brush.... GL

I agree with all the above...also, what material are the rings made from? The sparkle brushes indicate metal, but they have a wood like construction. The edges of the birds could have been softer, making them blend better and look natural in the setting.

Just a few minor things that might help. good luck
