I have a Tumblr now. I will likely use it more for posting pictures, and use DA more for talking and RPing. My handle is the same, just look up Oaky or Oaky123456.
Only really look it up if you want to see a more constant stream of art. Its sadly pretty difficult for me to post pictures on DA. I have to go through a whole annoying process, and it's easier and faster to use Tumblr. Besides, finding an audience on Tumblr is easier. Like I said, DA will be more for talking to you guys.
That's all.
