Sorry for the super late reply. I got out of the habit of checking my DA page. Nah, sadly I don't have any videos or tutorials. Best I do is occasionally go live on instagram (user:epoole88)
I left a comment on one of your Seattle Seahawk drawings asking if I could get permission to put it on a t-shirt ( my son plays little league football and I would like to wear it to games) ? Love your work!
