Pleasure man! Your entry was really good, if I may, as you said that you like constructive criticism, I wanted to advise you to do the outlines of the whole lettering with the black marker like the one you used for the background and overlines, it's only because the black outlines are very thin and the lettering might not be that visible and you don't want that to happen because the whole piece looks very good and I'm sure with a thicker outline would be BANGING! ahahha
Respect and really happy to have a new graffiti mate ahahah Cheers! 😎
