I'm loving what your doin man. I plan on helping out as well. You've inspired me to try this style out too. Anyway, I think you should consider resizing the characters, really its only the height im concerned with. Instead of it being 1.07 or etc. it should be just 1. Just match them to most characters in that style and you will see what i mean

Feedback for Human Torch
-Hyper 3400 doesn't always hit properly.
-The sound of his fireballs seem off
-The intro where he lands if you hold down he keeps on rising for some odd reason
-He needs more voice overs in him. The character feels a lil empty without it.
-Some of the voice samples seem a little low in volume
-There is no fire Fx or palette FX on p2 whenever they're hit by fire

There is a way to make the fire go over his body like it should.  If you want to give it a try then check the spoiler out

Spoiler, click to toggle visibilty

Change the sprpriority to 4 then it will be over his body

Change your Fire Helper to this in the -2 state
[State -2, Helper]
type = Helper
trigger1 = time =0
trigger1 = numhelper (1) = 0
helpertype = normal ;player
name = "Fire"
ID = 1
stateno = 1
pos = 0,0
postype = p1
facing = ifelse(facing = 1,1,-1)
keyctrl = 0
ownpal = 1
size.xscale= 1.5 * const(size.xscale)
size.yscale= 1 * const(size.yscale)

Then go to state 1 Paste over what you already have and tell me what you think

It's not perfect but it makes him look a lil better in my opinion if you want things to be a bit more transparent. The special move fires can be High res'd and put in to complete this process. The Fire Beam like hyper, you can simply cut that off from that sprite, high res it and put it back on.
