1) Design is nice and a coherent aesthetic but some of the pictures are a little pixalated, mostly the second and last one
2) It might be hard to get the text to go above the characted when there is not space already there above it.
3) It might look nice to have the text for maybe just the second one be another color other than black, like it could be the pink of her hat or maybe a lighter green like how the first one is a lighter blue.
