I love the subtle details in how each of the girls is drawn here. Mami is holding the can and brush similarly to how she would her teacup and saucer and also has what appears to be a lily blossom painted on her clothes, which calls to mind the floral elements of her soul gem and hair accessories. Kyoko, who normally wields a spear, is holding a long-handled roller in much the same fashion. Sayaka is similarly holding her paint roller as she would her cutlass, and her bent leg is on the right side, where the hem of her uniform's skirt would be higher due to its asymmetry, not to mention that she appears to have a concrete shape of some kind painted onto her clothing, indicating her intent of succeeding Mami as the protector of Mitakihara, and she's the only one whose outfit does not feature a breast pocket, which probably means something as well, but I can't think of it right now. Homura is holding a spray can, evoking the firearms that she normally uses, and is the only one wearing a long skirt as opposed to the other girls' shorts, which calls to mind how she masks her feelings while the other girls wear theirs on their sleeve. I'm sure Madoka has something worth noting as well, but I can't think of anything right now.
