What's the artist's intention here? All I can think of is Anti-LGBTQ symbolism since that's also a common image for people to use. But I hope it's not, it looks so cool.

It looks innocent enough that it should get a pass, in "Umbrella protector against evil diversity" works it's canonically the patriarch of the family who carries the umbrella.
This art is indeed cool 😎

It's random colors and not any specific LGBTQ flag. Either way, colors being seen as a good and nice thing independent of that still makes it seem odd. It feels like it's trying to say the kid is shielding themselves from good.

Thought the space invader mosaic might mean Manchester, but seems like that guy really gets around too.

This is beautiful

Nice

Great spot. I missed that and I took the photo! Not Manchester. SW9 London

This vibe from it

Ah, that also explains it looking kind of familiar.
