I'm in the process of writing the next chapter of my story, and it looks like it's going to be longer than normal. Should I keep one big chapter or break it into two different parts?

I have been thinking about putting a picture with my story, but lack the necessary skills and tools to make a good drawing. If there is anybody out there willing to draw this for me, that would be greatly appreciated.

P.S. I won't be able to pay for this. I'm asking if anyone will do this as a favor.
