Aurelia is ok, but doesn't really fit the build well.
Esper sentinelis a weird include. Your creatures are very important so adding other effects as creatures makes you more vulnerable to things like board wipes that already might be cast against you.
I don't know how useful Ragavan will be. After turn 3 or so he probably won't be able to get in.
Consider seems weak. You want your spells to either be impactful to the board or replace themselves.
Shock seems weak as well. Lightning bolt is borderline.

Something to keep in mind with the couple "utility" creatures you have: you don't want more pressure on your powerful creatures and you want noncreature spells. So if you can find a way to get the same effect some other way you might want to.
The two man lands and the two bad fetches aren't great. There are some more untapped lands you can use or maybe some utility lands.

Some cards to consider adding:
Past in flames - Lets you recast spells from your graveyard. If they have rebound then you'll get them back in the graveyard after the 2nd cast.
Quicken - Single blue to turn a sorcery to an instant and replaces itself.
Runechanter's pike - +x/+0 for the spells in your graveyard. Also there's a 3 cost version, Glamdring, that lets you cast a spell from your hand for free potentially.
Primal amulet - Makes your early spells cheaper, then lets you copy spells later for free.
Some planeswalker - Any that fit what you're trying to do really. Draw cards, copy spells, etc. It adds another type of thing people have to deal with.
Snapcaster mage - Cast a spell from the graveyard again. possibly at instant speed.
