looking through your animatic, try and get an ambient occlusion pass going on just the frog, the inside of the mouth is too bright. I also think you need to bring some specularity into the skin. In the opening shot, the clouds feel too flat on the sky, get some perspective into the matte painting, and and some brighter whites in parts of the clouds to give them depth. The jungle is definately too black in parts of the background, and I think your next goal is to lighten some of those areas up as you plug in more shots for next week.
