Really loving the poses used and the interplay between the blue and red! Though for some reason the image overall just seems abit floaty - while the character in the foreground is in midair, the other also seems to be floating somewhat. Perhaps (methinks) its the lack of a darker visual accent to ground the figures, I think perhaps if you applied some form of shadow below the characters they would have a bit more weight and in turn balance the image overall? Also nice to see some application of graphic design elements to the illustration, helps to make it pop, though I think there's definitely more room for you to push it even further. Still, that's just nitpicking, great work overall - nice stylistic graphic design elements, good forms and tones! Keep it up!!
