Okay, Devoid, you are talking about a few different things at once. Let me try to be brief and amazing and explain what's up.
#1. Look over the Resource Specs. It is in your help file, and here, online.

#2. Now that you know the difference between a spriteset (3 by 4 for each character, or a sheet of two rows of them, four sets in two rows), a portrait and a battler (single pictures) you can talk about cutscenes.
What you posted is a small battler. It doesn't slash swords. However, you can show an additional resource, an animation, to show (for example) a lightning-like slash across the screen.
If you want a sprite to slash a sword, you need multiple character sprite edits (check out my example) so you can show him moving around, with a sword.
A famous set of sprites which move are by Kaduki and look like this.

As you can see you'd still need to add a sword.
An entirely different approach would be to use standard sprites and just use special animated battlers.
Like these at left, or ones by Holder...

But really, I'd suggest you play some games. Become familiar with what is out there and being done. =]
Good luck.
