> I had no idea that he felt this way before the meeting
Meaning, your manager did not say anything about her boss being disappointed with how long things were taking?
> I have no clue what happened in that meeting and I haven't heard anything about it from either of them since.
This and the observation above, assuming it's true (that your manager never said anything about her boss being disappointed), makes me think you might be putting more weight than necessary on what happened in the meeting with your boss. At the very least, you might want to double check.
One way to double check would be to ask some coworkers for feedback on your manager's boss and his communication style. Are the kinds of things he said in the meeting with you signs that he's really disappointed and might ask your manager to take some action, or are they just spur of the moment things that don't imply any longer term consequences?
Another way to double check would be to schedule a 1 on 1 with your manager (if you don't already have regularly scheduled 1 on 1s, otherwise just use the next scheduled one) and say that it looks to you like the project is pretty much done but you want to make sure there aren't any loose ends. Then briefly describe what you've completed, and what still needs to be done, and ask if there is anything else that you need to do to finish the project off. During your description, you should mention the key criticisms that your boss had and describe what you learned from them and how you are hoping to apply what you learned to your next project. Your manager's reactions and feedback during all of this should be informative.
> it feels like an inauspicious start
Actually, for a first project in your first job out of college, you should expect to make mistakes. We all do at that stage of our careers. If at the end of the day the project is done and meets requirements (and I'm assuming that's the case here, since you say the deadline was moved and is still in the future and you say it's pretty much done), overall it's a success. The real question here is how your manager and her boss deal with the fact that you, in your first project in your first job out of college, made mistakes but still ended up delivering a successful project. Good managers and bosses recognize that newbies will make mistakes, and will be looking for signs that you learned from those mistakes so you won't make the same ones on your next project.
