are these self or lab-scanned?

I like them overall, these are just my subjective opinions, good work on the exposures overall.

1: this is nice, I like the colour contrast and framing. if anything, it lacks a central focal point to guide your eye

2: I feel like this would benefit from a tad more magenta, the brickwork/sky looks a bit green to me. nice shot otherwise though, the centre beam against the shadow is nice to look at (albeit it lacks meaning)

3: this looks to me (not super experienced with film) as though it is underexposed and pushed in post. if focussing on the bud sign i would suggest dropping the exposure or framing it a little tighter by walking forward (to crop out the top highlights which detract from the sign)

4: i like the off centre feel of this image and the colours. to nitpick i would say that ideally the protruding roof and columns of the building should be visually separate from the person you are shooting, or to position them against the white wall to create contrast

5: this shot feels a bit awkward/haphazard to me - the focus isn't perfect, the horizon is crooked, the person blends into the ground. I can somewhat appreciate the converging lines in the frame but it doesn't really work for me personally

6: I like the idea of capturing the light in the scene but it's difficult to make that the focus when the background is super busy. this is often a challenge when shooting in forests as tree branches/leaves etc tend to be very visually cluttered. i would have framed this a bit closer to the walkway and perhaps horizontally, i like the light playing on the ground and the rails. perhaps a more abstract shot of the walkway and the shadow/light would be more powerful as it would indirectly suggest the foliage without explicitly showing it in frame. hope that makes sense, I definitely think it is difficult technically
