I might be wrong but in my eyes Sweden is full of it.
I respect anyone doing graffiti the way they want, but I really hate this style.
For me it's like u don't give a shit about even trying to make it look or have any symmetrical elements, or even do straight lines with the same thickness.
But anyone should do it the way they want.
If I'm not mistaken this style evolved, at least in Sweden, because we always had a lot of surveillance on the trains so writers never could do the same thing or evolve as in the states.
I might be wrong!
Just came back to the culture 2 years ago so I can't say I know it all.
