Okay, I NEED COMMENT ANSWERS PLEASE! Almost all of my art trade slots are filled, should I add more slots?? DX

Hi there! I decided that to work on my art skills, I'm going to have to draw more. So I am doing requests. I don't do commisions, and art trades are also in the subject, but I am going to mainly try requests.
--------------------------------------

RULES OF THE REQUESTS
Nothing Inappropriate A little Gore is all I'll go up to.
Please just comment me your request.
Even if I know who you are talking about, give me an image. :3
When saying your request, please realize that I am not the best artist, and that this is mainly for practice.
This is mainly for practice for me.
These will all be done with colored pencils and paper.
I will draw anyone or anything.
Also, for what I want in Art Trades is a chibi picture of Tobi! X3
