My home base is only 3500ft runway
Gosh! Heaps in a PA28! That's around 1,000 metres in real terms. I don't know where you're based but I seriously suggest that you go with an instructor to a more limiting aerodrome, perhaps with about 600 metres and get proficient there.
Also, as others have said, that's a pretty decent horizon in many of those pictures. Unfortunately, a beautiful blue sky when viewed from the ground when there's high pressure usually means a less than gin-clear view aloft, but it looks like you had very good conditions for your flight.
TOO.
