Looks like your off to a great start. It's been said already, but stay away from the middle for a bit and try to get the outer limbs bending a little more.
Be sure not to leave it on the tiller stick any longer than is absolutely necessary. You just want to get a look at the tiller and then get it off of there 'cause the longer its held drawn the more stressed it will be. And that translates to more set.
Good luck and have fun.
