Analog film photography and cameras

Cool picture shame about light leak, are you sure you agitated tank with fixer bath too? The vertical streaks on the sky can be poor/ if any/ agitation during fixing stage, or light leaks. I can't tell from this pic what is the case but you could try fixing bath again.

Cheers, I was gutted about the leak but quite like it now. It's on 6 rolls of film so probably forcing myself to like it!
It could have been agitation during fixing, I'm not as rigorous during fixing but do still tend to agitate pretty well.
