So in an attempt to draw them in or juice them for jobs, big productions are done. It's definitely nice to see a big wall with a theme, it undeniably looks nice. Ultimately though, my focus is on the letters. A 2-colour fresh piece to me is still more appealing than a big production. The focal point should always be the letters.
Some paints are definitely better than others, but all can be used.
Personally Beltons pretty much have this shit locked down. Marabus were considered to be the cream of the crop for a long time. They still have some fresh fresh colours though. The Krylon company should just blow the fuck up. Just another way to get up more than anything.
