I can't immagine what your art would look like with an actual tablet! I know that you can get some tablets for pretty cheap. Mine was a Bamboo from Best Buy for like $99 and that's actually super cheap!
Although I have one, it still is really hard to sketch in a way...it is easy for the lines to become messy or create lineart that is really smooth. Some people can do it like it's nothing but I've got a long way to go haha!
I already loved you for your femshep, and then all of a sudden cassandra cain? I am not worthy. You rock, probably my favorite cassie image ever other than 89g's cassandra images. Keep it up, more cassie woooo~
