lot of different frogs donated bodyparts for the froglloon.

Lets see:
obviously the balloons were dyed green (hue/saturation, curves).

The air-bag (dont know a better vocabulary for this organ) was also dyed. In red.

I used layermode overlay and also layermode "normal" with a layermask (for igher opacity) for three things:
- create the sky-reflection on the ballon (part of the sky was copied and distorted for that)
- create a few frog-reflections on the balloon you will only see as colorspot in the final result
- create a "airbag-organ" reflection on a balloon.

I also used layermode color for change the eyes to red and stained some details on frog and balloons.

I used white brush to soften the sky and black in combination with layermode overlay to darken the edges a little.
