This should probably be in the Creative section or in the Feedback and Suggestions section.
That said, regarding the bard:
I like that he is very focused on creatures. The Bodyguard ability is very strong, since Vigilant is a fantastic trait for creatures with quick attacks because they can attack and then counterattack on the other player's turn (currently only Togorah, with a full attack, has intercept). You might want to make Singing cost at least 1 mana.
The problem, of course, is that he has no spawnpoints, which means he has to summon all of his creatures himself. Therefore he wants to go for a few big strategy (particularly given his excellent bodyguard ability). The Charisma ring will not pay for itself until he has summoned at least 3 creatures which, given his channeling and aforementioned lack of spawnpoints, seems unlikely.
As far as balance goes, level 1 arcane and (should he choose it) level 1 water gives him cheap access to all of the basic toolbox spells. Coupled with his lack of antitraining, he is even more versatile than the wizard, since he also has access to cheap curses (from dark) or healing/protection (from holy), to buffs (from nature) or strong defensive creatures (from war). With these savings, he can afford many higher level spells in any school in which is is not trained, especially since he only pays double cost. Furthermore, he has access to a variety of school specific spells in both holy/dark and nature/war schools. The unrestricted nature of bodyguard also has the potential for some disturbing combos - imagine a vigilant Iron Golem, or a vigilant Darkfenne Hydra. I suspect a bard would be stronger than the average mage. He certainly succeeds at being an all-rounder, though.
I tried my hand at making an all rounder, with a slightly different emphasis:

He solves the problem of diverse training by being antitrained in all medium or higher level spells (partially mitigated by his ability to reuse spells) and being hobbled in his movements.
