Thanks guys, I appreciate the kind comments!
Mudder, they were landscape orientation. I'll eventually try protrait ones, but basically did them rather quickly just so I could try it out! I perhaps shouldn't have used 18mm on the kit lens either due to barrel distortion, but I don't think it's too obvious

I might one day invest in a pano head, it certainly makes sense, but at the moment I need to expand my glass!
Gordon, your panos are gorgeous! I have the grid on my viewfinder on all the time too.
I'll keep trying and learning, and I'm actually really enjoying PPing too. Still have colour cast issues, but I think I've learnt to overcome them......
