One is plenty!

Two is okay.

One of each type of media: digital, pencil, marker, watercolours... (means 3-4 pieces a time)

As many as you want! I don't mind! Love them all!

None. Just post the end result. That's way more interesting.

If you can keep yourself from typing too much text, I won't mind how many.

It's not the journey that's important, it's the destination.

Evolving images... never thought about that! I'll do it too! (You go for it!!)

What the heck is an evolving image? Is it about Pokémon?

As many as you want, but only 1-2 on your front page is enough!
