Grunge?

Grunge, a litte bit of punk, goth, and maybe some deathrock too

It's giving punk/grunge. also it doesnt even fit into emo, why does everyone call everything that's all black emo. but yeah, it's sort of punk, so definitely alt

For me, thats grunge with a little bite of e-boy

Punk-ish

Let's create a new aesthetic for it

.any ideas for making it more urbancore?

I think you gotta add more color and some "graffiti" stuff in there. I've taken a quick look at the outfits of Urbancore and it often have color and something spray-paint-y.
