I've been busy the past couple of weeks with my sister's wedding, but here is some of what I've been working on.
I didn't really have a concrete design in place for Hera when I started working on her design, but I knew i wanted her to be regal. I really like her final design, but it looks like I might have drawn her about a head height too short.
I've always seen Apollo as being a bit of a jock. He's kind of the perfect guy, smart and athletic. I also picture him being ridiculously tall. I tried to make him as "square" as possible design-wise since he is the stable one compared to Cupid.
Artemis is athletic and confident. I finished Apollo's design before hers, so referenced his design when tightening hers up. I might still be changing her hairstyle a bit, as I've realized that she looks a lot like the Artemis from Young Justice.
