How am I doing?Follow

I'm new to WoW(Well relativly new anyway) and was wondering was there anything I needed to change or improve on my mage(My main Character). I know I need to change my talents a little, but I can't figure out where. Right now I'm just mass AoE grinding trying to get to 58 to head towards outlands XD. Just wondering if there was anything I could addjust easily?
