Does 'it' in the question 'what is it?' refer to the shipping container, or the thing space helmet guy needs to discuss? I'm assuming the former because that's what makes the joke work, but it seems like it would be more natural for it to be the latter.

You've got a good idea for a comic here and I enjoyed what I've seen so far, but make sure to avoid ambiguous pronouns that muddle the comic. And also watch for grammar, particularly in the first panel.

Looking forward to the next one.

Thanks for the advice I'll keep it in mind.

And 'it' refers to the container, i hadn't even noticed you could read it differently.
