Things to think about
the postcard with the chesire cat - the text will jump from top to bottom while swtiching sizes, could be confusing
all the postcards are minimal, but not minimal enough to truly be minimal; aka, either embrace the minimalism or make them less flat than they are now with color, less lines, etc.
since the two font sizes are so different, I don't think you need the dash in front of the character name, and it would clean it up a bit
as the cards move more towards vertical from horizontal, think about the placement of the drawings and where they will go; the mad hatter and alice postcards especially - are they going to move down while the text moves up?
the text and lines of the drawings are so similar that my eye sometimes gets lost in them and I'm confused about what to focus on - could be solved with different photos, or you could use a stereotypical sans serif cartoon font in a different color
in some versions, I think your text needs to be integrated with the photo more, and where I'm seeing the lack of this is in the horizontal chesire cat one especially
it could be interesting to include a drawing that directly depicts the quote, just in case the viewer hasn't seen alice in wonderland (doubtful)
all in all, super cute postcards, but they need a little something more - color, detail, etc!
