Very interested. I am also having a hard time finding advanced level writers, and most of the people I run into aren't very active. I am more of an artist myself. I do a lot of work with graphite and ink, some watercolor, and also I do a good deal of work with photoshop, and I also like to add a lot of visuals (I try to use my own original work as often as possible). I love to write and create characters and settings, and I prefer darker, and more mature type themes as well. I usually check this site daily, and the lack of activity I am getting is tiresome. 
I am very creative, and I only do advanced, descriptive style rps. I would love to collaborate with you some time.
