I like your PC and your lack of powergaming ethic. It seems that the people I end up playing with always seem to know what feat they are going to be taking at 15th level, and you can't even decide what you're taking for your third feat. I tried this similarly, as well, recently. I came up with a character concept and how I wanted the character to be, and all of the statistics came secondary. He's now a shaman 1/psion 1, and he's so close to third level I think I'm going to take a level of druid. I don't need to focus on one thing, and I like not having to think "Okay, I'll take combat expertise so in 4 more levels I can be a holy liberator" or whatever.
