Just signed up for that too, so if you're not following me on Instagram, tumblr, facebook, or twitter, you're missing some art that I'm not posting here! #GetOnIt!!!
If you want to find me on instagram my handle is davidyardin, just as it is elsewhere online:
EDIT: Just to clarify, If you are already following me on any of the above services you will get all my feeds since I have linked them. If you are only following me on deviantART you will only get art I upload when I'm at home (so pretty much no con sketches, or anything else while I'm away from my home setup). I don't expect you to follow me on everything, but I'm letting you know where I am if you use those services, and want to see all my art.
