Very messy ballpoint pen drawing

I haven't drawn with ballpoint pen in five days so it was time i revisit one of my favorite method of drawing. Unlike what i normally do which is first sketch with pencil so i have erasing ability and then move on to ball point pens, but this one i started with ball point pens. Which is why there are some huge anatomical mistakes in the drawing. I tried to fix them but it got messier.

One more thing i would like to share is that, i am working on making a sketchbook by myself, i am cutting up all the huge art papers and have some plan to get them in the shape of a sketchbook. I plan to fill that sketchbook with ball point pen drawing only.
Wish me luck so i can actually get that done. I am gonna need it because today i am in the mood but tomorrow i might burn all the papers.
No idea what i am gonna do.

Here are some process shots for this drawing:

I used this Reference image for this drawing, although there is literally no similarity between them....
