Very interesting.
Let me express my feelings for each:
Kitana: Interesting, and rather creative.
Reptile: Also pretty interesting, but nothing great.
Sonya: Creative, and pretty cool.
Jax: A bit repetitive, but it was also good.
Nighwolf: Creative and interesting. I also think he should have gone boom, though.
Jade: Awesome! That's a great fatality. Still... she has two staffs?
Scorpion: Quick and to the point. Not bad.
Rain: Predictable, but still interesting.
Kano: Looks like Kabal shouldn't have been wearing them cleats. =3
Maleena: Hell yes! Just excellent!
Ermac: Better then his original fatalities, methinks.
Sub-Zero 1 & 2: Both are quite predictable, but well executed.
Noob Saibot: That was very interesting and brutal looking.
Kabal: Another excellent one, even if a bit predictable.
Sindel: Interesting and not to predictable. Also a cool effect.
Stryker: Kinda random, but it's cool.
Cyrax: Another very good one, and pretty random to boot.
Kung Lou: Can't say I saw that coming.
Sektor: Pretty much the same as Reptile, but not bad.
Sheeva: Way to predictable and repetitive.
Shang Tsune: Very good and a very interesting effect as well.
Liu Kang: Kinda remind me of that one fatality from the newer MK games. Not bad, though.
Smoke: Pretty good, but what did he drop into Sektor's mouth(?)?
Overall, a great flash. Keep up the good work.
