Thank you for the birthday wishes! I've not able to upload any new art because the submission page on deviantart doesn't work any more. It just keeps coming up with the error message "You must select a mature option before submitting to deviantart" even though I have. :/ I googled it and I can't seem to find a fix.
Edit: I managed to fix it by disabling all my browser add-ons.
And you can buy my work on t-shirts at TeePublic!
