I actually really like Luke. It shows the difference in how people react to hard situations. Luke and Thalia both have really hard childhood experiences. They both lack the parental support they need. They both have the same choice to make about whether they will betray their parents. Luke makes the wrong choice. I honestly think he mostly has good intentions. I don't think he completely know what he's doing when he joins Kronos army. That's just my opinion. By the way, I love the art!
Your drawing is great, but after everything he's done, I just want to throw darts at my computer screen! I LOVE YOUR ART! So, my little emoticon doesn't relate to you or you masterpiece, it relates to Lules character.
