I think that any photo-sharing platform is good, be it Flicker or pixelfed or whatever, if it allows people to see your work without signing up (like Instagram does). I also find that Ficker has a pretty good community and a decent amount of users. It’s worth looking at, unless there’s anywhere else that your photos are collated anywhere else online for me to see. From what I’ve seen from your profile here, it’s definitely worth you having a place to let people browse your work
