Welcome to CG Planet.
Despite rough sketches, they still deserved to appear in actual form.
Perhaps you may need to a tripod to mount your DC so that you won't created
motion-blurred photos.
Looks like you are a big fans of Naruto or Bleach?
Although doing on rough papers is fine, make sure you have removed details of information you are not planning to show at the same time... like the last one.
The first one is nice. OThers... you probably need to work more on character drawing to sort out some general proportion issues.
Good luck.
