Yus, the patterns are called screentones - I have dots in tons of sizes and with different spacing, speed lines, bunnies, kimono patterns, sparkles... I love this thing. *squeals like an idiot* ♥

Shadows from a single lightsource ARE easy! Not that I was great at it but it works well enough. After practicing for a few months, it comes naturally! *cheering for you* \o/

And YAY for free time!! :DD *hugs*
