@Kaostantine:
Now I understand. I figured that was what you were intending when drawing the cloak. It's interesting, but that style of clothing is unusual for Sypha. Now that I understand it, I can see what you're trying to do. Conveying this idea in a tiny 24x48 sprite is going to be a challenge, however.
On your point about not having access to the game engine, you still have creative control in terms of telling the programmers the duration of a frame of animation. I've worked with people with access to Game Maker, MMF, etc. while I myself don't have access (or, at the time, did not have access) to the development environments. When that would happen, I'd usually receive a video from the developers and would say "No, that frame is not right. That frame should take less time than other frames", etc. This allows the developers to tweak the animation duration for any particular frame, improving the work. Usually you can be generic, saying stuff like "See that frame? It takes half as much time as these other frames". Stuff like that.
I'm going to share with you the animation I was going to use in my game for Sypha. I went with a "Keep It Simple" design.
Normally I don't share until I'm somewhat complete with a set of sprites... but my game isn't going anywhere for a while, so I suppose I can share a little. Maybe it'll help you? I don't know. At least, it'll give you ideas.
I'll also put it up on the sprite request & showcase thread.

As you can see, in my sprite (based on the CV3 sprite and the SotN sprite), Sypha's cloak is separate from her robe. However, when casting a spell, she holds her cloak with her fingers a little, not unlike how Dracula holds it when he's doing his dark spells, or how Alucard does his Hellfire in his first frames in SotN.
The wind-up is quick, but the follow-through stays on for about twice as long as the other frames she uses.
She doesn't need a big follow-through animation either, since it's the magic in her staff that's doing the damage, not how hard she thwacks something with it.
Pepper her staff attack with a few key particle effects (magic sparklies, lolz) and she's good to go.
