Hi, SVS community responding . I only have a suggestion. Your wizard's scarf may add interest if both flying ends don't look almost identical. Maybe one catches the wind slightly differently (tilted more behind the other). Though I am not certain if this would be contrary to what would happen in reality (that's why it's a suggestion). That and his feet placement -seems very static (he might fall over (he's also creating a windy environment) because he's not grounded so well) -one leg ahead of the other and maybe with some bend.
Other than those I really quite like your character and his journey.
