Drow Dragon Disciple

[graymachine]

I'm building a character for a new game and put together the following to see what it would look like. The game is limited to the Core Books and the class variants out of UA.

Race: Drow
Class: Battle Sorceror 3/Paladin of Tyranny 2/ Dragon Disciple (blue) 5
ECL: 12

Str: 20
Dex: 13
Con: 16
Int: 12
Wis: 10
Cha: 20

Fort: 16
Reflex: 9
Will: 12

SR: 21

claws and bite attack
2d8 Breath Weapon

Spells: 4 0-lvl, 2 1st, plus bonus spells

I haven't bought equipment yet, but the build so far seems as though it isn't working very well. What does the playground think? Things to change?
