Well, the responses here have been incredibly mixed. Thank you guys for the feedback, you all raised good points. I'll try to address most of these eventually.
For the time being it seems the consensus is that Ismael's sprite sticks out the hardest now that Greta got upgraded, and I have a bit of time while the writers finish editing the last chunk of content for 0.6.0. So...
Here's a comparison between the old and new sprites.
It's also an opportunity to show off the gothic script uppercase "E" in Ismael's graphic tee a little better. Don't know if I've ever mentioned it but the sweater hides two more letters to the sides of the E (L and F), which spell "Liberté, Égalité, Fraternité". Between that and the color of his clothes Ismael is... French. He's very French.
