I was just looking at the cover of Tasha's Cauldron of Everything, and it made me realize what this new wizard illustration is missing. Tasha is shown actively casting a spell, like it's her turn in combat and she's doing something badass. In contrast, this new wizard is just floating around, surrounded by spell effects, waiting to react to something. She isn't even visibly controlling her spells. She's just kind of floating there, doing nothing, while the trappings of a wizard surround her on all sides. The spell effects look way more badass than the wizard herself.
If they take this same approach with a druid, we're going to get an illustration of the new druid just standing in a grove, striking a self-aggrandizing pose, while animal companions and summoned elementals run wild around the periphery of the page, looking like they're ready to tear into monsters. Hey DM, can I play a badass, snarling wolf like the one behind that boring, pretty person who's just standing there, passively modeling a green cloak?
