I'd be OVER THE MOON! I don't know what I'd do, but I'd keep working, trying to engage and interact more with fanbase and prepare all the physical merchandise I always wanted to do xD
I'd also rush here and thank every single soul who subbed to my story and kept it alive xD
And, of course, keep working. After all, my comic is almost all written down in script, so I already have an ending to it, and I intent to do it in the most fitting, respectful and deserving way to honour my comic!
