Rachel's been doing an excellent job of keeping our animatic up to date with all the most recent work we've been doing. Here is the most updated one so far.
We've now added the 2D clouds (Option B won outright) and I have to say I am very surprised at how much the overall look of the animation has improved. I didn't see it before but not only were the 3D clouds distracting they were also blending the animation together too much. The 2D clouds now look like they are in the background and are much more subtle than the previous clouds, allowing the focus to be on the characters which now seem to pop out a lot more.
I'm also glad I made them transparent because they look amazing when they go through the 'Jump' title (or when the 'Jump' title goes through the cloud). I do need to draw some more clouds from another angle for when the characters jump out of the plane but that's not urgent right now.
