What a great expression. I also love the way the messy diaper is illustrated - a nice big lump, but not a huge brown stain. Kinda more realistic that way.
I’m not even a huge fan of Gilda, but this is amazingly well done and I can’t help but really like it. I especially like the faded designs and amount of detail on the diaper in general. I feel like she could use some eyelashes, both to stay more on-model and for my own personal preference, but really that’s just nitpicking.
