You probably didn't know this, but my son is a huge DSi fan. He's got a dozen of them. He buys, repairs, and sells them, hacks them, makes them do all kinds of things like controlling my Roku, web browsing, video calling, and stuff like that. He's even got twice as many facebook likes and something like 15,000 people trying to serve flipnotes on his reverse-engineered DSi flipnote server. I think he will appreciate seeing all those DSi's on this illustration, but he'd probably ask why you didn't include a black DSi, or the yellow limited edition Picachu DSi in there.
As for me, I think it looks cool. I do miss the mermaids though. I hope the one-eyed mermaid comes back somewhere in the story somehow, some day.
I was actually careful to only include the colors that I and Marah own, since those are the ones I show in the comic. But that's pretty cool! It's neat to see what people can do with tech beyond just what was intended!
