You know, I am probably one of your biggest fans. I am always excited to see one of your new Monster Hunter pieces so I can share it with everyone on my MH FB page. Trying to become an artist recently somewhat opened up my eyes. I noticed how people would post your art and give you no credit and it upsets me. I understand the feeling now of working on something and then just having it stolen /:
I usally sketch at 72 dpi on whatever screen resolution I happen to be in front of at the time More polished sketches can be anywere from 1000 to 3000 px wide or tall for finished work I work 300dpi letter sized or A4.
