Hi reader, last week I bought a Koi brush pen in a bookstore, and this is the first time I use brush pen, and I really hard to make clean lines. I can't handle my shaking hand. But it doesn't matter because I'll execute it in vector program. Lettering art is really interesting, I'll keep practice to make great stuff.
Btw, I make this lettering to present my new domain : TeesLab.com
