1: Orbit-y hand thing:

Good: Looks awesome
Bad: Invisible on white background, and it would look stupid if it wasn't additive

2 Another orbit-y hand thing but a little different:

Good: Looks good on a white background, orbits in weird caustic-like motions
Bad: Sort of boring, scatters around a bit much.

3. Archon glow:

Good: Looks okay on white background, blends better with everything than other flames.
Bad: Might look weird with the wrong texture set, not very original

4. Body spiral thing:

Good: Looks awesome, very original/unusual.
Bad: Slightly interferes with gameplay, invisible on white background.

Respond? I can't decide. Hopefully this is allowed here...
