Oooh, it's so pretty and sad. I love your Regulus, especially the look on his face in the sixth panel. The way you use highlights is beautiful and distinctive. Love!
Concrit? Ummm.... Uh... I guess you could have distressed the swirls, or compacted the panels and removed the swirls entirely for a less-designed look, but seriously, it's lovely just the way it is. Wouldn't change a thing. :D
