When I did a write up a while ago, it started at a d4, so at level 5 you get d6, 10 is d8, 15 is d10, and you get d12s at 20. Yours would cap out at d12s by level 15, but either way works fine. The important thing is the # of dice, and the abilities that key off of them. Having dice scaling in number alongside spell levels makes it easier to balance the power of the abilities that key off them, and thus is better all around.
