Awesome! Glad to hear it- feel free to start submitting art whenever.
Also, I'd just like to say... if growing out of KH or anything like that had to do with your leaving, you should come back. TKK is changing focus from KH and focusing more on being a general content kind of site, and we've been more active than any time in the past couple years or so. Lots of exciting changes going on right now... you should come back if you have time.
