Thanks!
I thought about adding graffiti but not only would it be a slog, it would probably clutter up the clean look of the game.
I studied a good few photos and videos to determine the scale, I feel as long as this is roughly accurate and the colours are familiar then the spot would be recognisable and fun to skate. Maybe the spots have just been built and we're the first to encounter them!
Or maybe if done properly by someone more capable, detailed textures would look awesome :)
I'm glad you're toying with the idea again, there's help here if you need it!
