Whoa, that last Lucca is phenomenal. My personal favorite can be found
here.
And take a peak:
Look at it! I just love the style--kinda cute, but not quite chibi. It reminds me of Legend of Mana (whose art I absolutely adore, by the way)...I guess that's why I'm so drawn to this piece. He started out with Robo and I think he colored it too, but when I saw Frog, this immediately became my favorite.
