I've decided to take the plunge, make an accoutn and start uploading my art, toys and printable characters here on Newgrounds after many years of using the site.
I've just uploaded a few of my designs, feel free to check them out, I'll be uploading many more in the near future.

Welcome to the party! If you upload one more piece, someone who is already part of the Art Portal can 'scout' you, allowing you the option of posting your work there.
