To be honest, not much of the last few pages should be in the intermediate thread, the quality of posts now is definitely a downgrade from the past. Focus on simple letters with solid structure using bars, cleanliness of lines (outlines, fills), and a small amount of style. There is no sense in jumping over basics and into bending letters and making extensions if its easy to tell your letter structure/knowledge of letter flow isn't that well defined yet. Yes important to practice and try out new ideas, but so are straight letters and the very basic skills of graffiti. You need a foundation to build off of.
Correction: Blitz was born in the 1970’s, started doing graffiti in the late 1980’s in Manhattan, then the Bronx in the 1990’s.
