Hi Danny
Looks a good job to me mate but it all could go horribly wrong...........
How do you know your concrete mix for the posts is correct.......?
Are they the right fence panels.........?
Is the fence treated with the correct preservative........?
You should have dug deep and paid for a professional fence installer, otherwise how can you be certain the job is done correctly? Seems to be the main advice given on here about all jobs.
But then plasterers can turn their hand to anything can't they
