Well how it's been going so far for me is, I just come up with ideas and write them down on a list and that's how I remember everything. I don't necessarily do them in any specific order, unless I'm trying to meet some sort of deadline.

When it comes to how many I have "left", there's not exactly a specified amount, because whenever I finish something I'll just think of a new idea and that process repeats itself.

And yeah, all my recent art are my own ideas because I stopped doing individual requests from people who asked. Instead what I plan to do is every so often I'll put up a journal asking for ideas and people can comment and I'll fulfill some of those requests. (Planning on doing that sometime soon during the summer)
