Reddit reviews Art of Hand-Lettering Its Mastery and Practice

In short, not really. Graffiti tags / handstyles, no matter how weird and wild they are, still have typography roots. Many quality graffiti handstyles could be compared to quality sign painting styles – a lot of overlap. If you're looking to develop a clean, refined, and traditional style then studying traditional sign painting would be my recommendation. Calligraphy, typography (the study of type in general), and drawing letters in a traditional format will all contribute to your knowledge of lettering in general. Then graffiti styles will follow after studying and practicing it more. After I started getting really into type, hand lettering, and fonts in general is when I noticed my overall tag styles improve the greatest. The rest is just a ridiculous amount of practice. Like going through multiple phone books, thousands of pens, and cans of paint.

Here's some links, I haven't checked all the books personally but I have a few of them:

The flow and layout is nice but overall the lettering could use some work.

• Work on your spacing and letter width. It is all over the place currently. Compare the width of the p to the o. Look how the p and the h overlap. The r is so tight it is almost not readable. Spacing and letter width are easy enough to make consistent and go a long way.
  
  
• In script letters downward strokes are wide while upward ones are thin. You have this right for the most part except in some of the swashes.
  
  
• Another general rule for script, dont let two wide sections cross. You do this on the uppercase T. Look here Basic example of how to avoid this.
  
  
• For the faux calligraphy only thing I noticed was the f is at a slant while the rest of the letters are straight up. Kind of throws it off.
  
  Good luck!
  
  ps: just a note. this book is where I learned most of these tips. It is amazing in the way it can give you simple tips to make your lettering exponentially better. I would recommend trying to buy it.
