For your info Lax is major good. He's going to college for graphics. Melo is amazing. He uses perfect blending with awesome colors. Probably has some of the best smudge tags I've ever seen. Buddah is amazing at GFX. Blending is amazing. His new style is unbeatable. He just makes damn good tags. Now me I'm not that good. I'm learning though.
You seriously need to get this. This is really simple. Takes no skill to make this. You need to follow some tutorials my friend. Maybe even some lessons.
