One thing, in regards to all these "review my build" threads lately: it's OK, but there's really no need to do that, as some of the regular "reviewers" are going to see it there anyway.
Back to the topic: Red wizard is a caster class. If you're not focusing on spellcasting... meh. It's not like you're gimping yourself, but you're hardly taking advantage of the class' advantages. Same for Spellcasting Prodigy and the Spell Focus feats. It makes no sense to take them and then leave your INT at 16 (you'll need items to cast high level spells, BTW).
Improved Critical is useless because you have a spell that grants the same effect for free. Rapier is a bad weapon to dual wield because it's medium. We already told you in another thread that Enchantment is a bad choice for your magic school.
Someone else will likely tell you the same there. This is a good build with the same classes (single weapon, though):
