I always enjoy looking back at my old art from time to time. Thinking about it now, quite a bit of my art (at least what's on here) revolves around people I may consider friends. Even though some have come and gone, the stuff I created around them serves as my connection to them. And artistic/personal growth, of course. Glad to see this is a common philosophy.
Anyway, looks like you're (sorta) new to these grounds. If that's the case, welcome to the horde!
