Job application feedback

Would anyone be willing to look over a job application for me? It's quite an ambitious stretch for me, so I could use as much help as I can get.

I'm looking for feedback on whether I've said anything that will be offputting, whether I'm failing to cover anything important from the JD/person spec, editing suggestions so I can bring the word count down a little, and general feedback on tone, style &c. Let me know if you'd be willing to give it a once over and I'll email it.
