There's an error in this sketched page that I fixed for the final version: notice Alfonso is holding the cards wrong. The way he's holding them, he wouldn't be able to tell the card number and suit (on the upper left corner). Suarez is holding them correctly
I noticed this when doing the cover, which for context, I did once I had about 15 pages sketched and 5 pages colored ahead of time, so I hadn't had to actually draw any cards up to that point. But here's the thing: unlike the other two, Alfonso is distracted by Walter, so it actually works as a little joke that he's not even focused enough on the game to hold the cards properly.
So, from here on out, if you see the cards being held like this, it's a deliberate sign that the character is distracted.
