Most of the good stuff I have to say about this comic is due to Martin. The colors on the ice/water that Sareena fires out at Ozais' burning hand looks cool and refreshing. Also, I think the idea of Ozais having control over smoke as well as fire is a pretty neat wrinkle into his powers. As Sareena chokes, her shield boxing herself and her opponent in begins to dissolve, and that only looks good because of the colors involved.
Pretty happy with this one myself. Should've darkened some of Sareena's hair in the second panel to show that it was wet a bit better, but hindsight I guess. The lack of words doesn't really give me much to say here I'm afraid.
Should note though that control over smoke is something Ozias can do that John, of WaR (who will be appearing soon), can't. That doesn't really get explored further for this appearance but something that might be worth looking into further uses for down the line.
