This feedback does not sound particularly constructive.
If they wanted something done faster or better: Well isn't that special? Look at the special boy who wants work to magically go faster with 0 additional work coming from higher ups or senior engineers. That's really nice, but that isn't how things work in the real world. Stuff takes as long as it takes.
If you aren't having regular, as in daily, meetings with your team to make sure you are working on the right things: That is literally your manager's only job. Do not let them brush you off.
Meetings are for YOU to make sure YOU are doing the correct work. It isn't you turning in your homework, it isn't an accountability check-in where you get a letter grade and a lecture. It is the time you communicate about progress and goals. They are YOUR meetings, to help YOU, NOT theirs!
Helping you with these meetings and other forms of communications IS YOUR MANAGERS JOB.
And if your team isn't considering changing requirements when planning work, then that isn't on you either. Requirements changes should go through your project manager and it should affect project scope.
However, at a certain point, you have to manage UP to get what you need from your team. Set a cadence of accountability with your manager and team. If they don't make that reasonable accommodation, at least you can say you tried.

As an aside:
Here is a fact you probably have not had to deal with too much yet: Some people are cruel assholes, and they don't even know why. They just say and do cruel things because that is who they are. Don't deal with assholes.
The other thing about assholes: They manipulate you. They make YOU feel bad for THEM. They make YOU feel like YOU are doing a bad job instead of taking on the responsibility themselves.
If I had a Jr engineer who was struggling, I would tell them and I would help them. If I had a Jr engineer who I forgot to manage and then they failed to meet expectations... well, i wouldn't behave like your boss. But shifting that blame downwards is a tactic you could use.
We have too much mobility in this industry to deal with assholes. If you are writing and shipping computer vision projects, cash the checks, keep your head down, get the experience you need, and once you are done with this place: Leave without looking back. You don't owe them anything.
