Somewhat new to this too. I would square around the whole thing and categorize as "other". I think another similar picture was seen before and others said was supernova (but don't quote me).

the only question to answer is "does it look like a bubble of some kind to you?". Like I wrote on the blog, there's no right and wrong answer to this question - we want to know your opinion. There's no fixed shape, size or colour for the bubbles, and it doesn't matter what might have caused it - that's what we (the science team) want to figure out. So if it looks like a bubble or a shell of some kind, please draw it!

but to address HearingStars' comment - yes, these kinds of red bubbles are often caused by supernovae or massive stars approaching the end of their lifetimes, which start violently throwing off their outer layers of material.
