8 hours is fine, but I know that you're not doing a sketch in 8 hours. You should give yourself a time limit and see how you go. I dont' suggest all your art should be timed, but say... 1 hour, or 2 hours. when the time goes off, you have to post the results. Maybe a 1 or two character picture. Doesn't need colour. I think you could do way more than you give yourself credit for. Your WIPs are all beautiful too
It's less that I refuse to do quick sketches, and more that after so long away, I've realized that my favourite pieces from before are the ones I finished. The ones I thought about, and spent the time on. I've done a lot of sketches in my time. They are the things I didn't stop. What I stopped was proper artistic study and completion of my work. I know how to do a 30-second gesture drawing, or a 10-minute pencil sketch. At this point in my artistic journey, I personally would rather take the time and be happy with my creations.
Thank you TuT Bryan has always used a bow and arrow as his primary weapon. IT made sense to make it fire since that seems to hurt the vampire the most Gotta make up for changing his element from fire to earth xD
