Constructive criticisms;
1) Your text leading is far too spacious, likely because you've set it to auto and haven't justified the lines.
Lower the auto leading section for your dialogue bubbles. It can finnicky with applying it to every text layer, so select all of the appropriate text boxes and do them all simultaneously to save yourself any hassle.
2) Small filesizes, subpar cleaning.
Probably the worst offender lately, even from big groups, is the lack of proper cleaning knowledge and technique.
I've already posted about how to do this before recently, so I'll redirect you to this comment.

As for the lack of redrawing and gratuitous stroke layers on floating text? Ehh, who cares about that stuff.
Otherwise, it's good for a solo project. Hope to see you get better over time.
