I've been trying to do the Compositing for this scene,
I got to the part where you added the blur and all I got was a grey screen. I cannot show you what my file is as I didn't save. I closed it in frustration. Also I found that all the nodes no longer have some of the options you talked about in the live stream. I really enjoyed this, but I got lost in all the nodes on the little Islands. I got this result and cannot figure out why the tree bubbles don't cover the whole green area like yours. my attempts at following weren't getting the same results. 38.36 was the time.
PS...Btw Its not letting me post my image until I edit my post.
