Based on the photos I doubt there is a non-instrument rated PPL around who hasn't done what you did without a concern, I know I did. Looks like a no question VFR flight to me
That said, endorse doing the IRR at the earliest opportunity, I crammed mine in virtually as soon as the ink was dry on PPL-amazing what the pressure of the threat of having the IMC withdrawn in April made me afford.
Agree with thing about flying on a horrible day (non icing of course) and breaking through into brilliant sunshine above cloud, puts a real smile on the face thinking about the ground based people trudging around in greyness!
The one issue I pick up from your posting is the flying with another pilot and having some degree of responsibility . I hate having anyone else in the cockpit who has a licence, I think it can very quickly put you in the incident pit.
