He looks like a typical greenie to me, jumping like the strange fences might bite him. Looks like a good job for your first cross country school.
In your flat work, focus on really making sure he's in front of your leg, so if you close your leg in front of a looky fence, you'll know he'll go.
Other than that, school lots of low, inviting fences to build his confidence.
As he gains experience and confidence, his jumping will feel less awkward and easier to stay with. In the meantime, get some velcro and stick yourself on!
