i actually second his idea of lowering the DC for the anyspell a little. your point is good, however, and it doesn't make it too difficult if you kept it there.
also, i hate the sorcerer's spell progression in the fact that they get their spells a level after everyone else. i actually see no point to it, beside the erroneous idea that the designers thought the sorcerer would be overpowerer compared to the wizard initially. in my games, sorc gets spells at same level as wiz, and i would (if i were making this), do the same here.
that reminds me, i don't think i posted that houserule at the watchtower.
awesome pic by the way.
other than that, nice stuff. this feels closer to how i always imagined the sorcerer.
