Oh boy, gonna try and keep this short. I love your stuff a lot!
The "lolXDrandom" humour of the early aughts you utilized in your toons influenced me a great deal when I watched them in middle school (much to the dismay of everyone who had to interact with me, I'm sure). Nevertheless, the Blockhead series has always had a special place in my heart and watching you improve with each episode was a joy to behold, and was very much inspiring to me as an artist.
It may now be well over a decade since your last real work with the yellow fella, and it seems you made the decision to fully retire him, but-- I know you probably get this a lot-- I'd love to see more. Maybe not a reboot, but just a little something. Maybe a goodbye to the series? Not sure. Anyhow, I'm ultimately happy with everything we got and I just want to thank you for creating one of my favourite animated series online to date.
Hope you have an excellent day, and I wish you the best of luck in all of your endeavors, no matter what they be. Stay cool, my dude!
