If anyone would be interested I have a 'sketchbook' account on tumblr.lithieu.tumblr.com/
It's still an experiment but I think it will be updated more often than dA.
Edit. Tumblr account is definetely working and I'm updating it quite often so feel free to join me there.
No, I'm not going to abandon dA. I think it will just have to wait for me to start working on something bigger.
