I've got some problems with my old Tumblr account and I can't retrieve my password (the e-mail I used there is now paid and costs a bunch) so I had no choice but create a new account...
In this new account I'll start to post, along my drawings, sketches, studies and reference material I used.
I'll be very pleased if you take a minute of your time to take a look! ;)
