There are a handful of graffiti writers in Bristol that I would group together in terms of what they paint and how they go about it. They would include TES (Slim Pickings), Phour, Pl8o, Bnie, Mena and in this example Mest, to name but a few. What these artists tend to do is write the same set of letters, usually in a similar font or style, but play with the fills and decorations. This is graffiti writing, but not wildstyle graffiti writing which tends to be much more elaborate and unique each time.
I think that this piece from Mest is very nicely finished and has some unusual but rather nice fills. I particularly like the pink dots that offset the rest of it. The green border helps to lift the letters a little. Overall a pleasing piece.
