Well, I took note of the whole dithering issue (I kinda thought I used too much on them backposes) and eliminated most of the dithering, leaving only the arms and just a tiiiiiiny bit in the hair because I liked it there.
I believe what's happening is that everyone is so overexcited by the looks of this pokemon ("ooooh look at the fiery holes on its back") that they forgot about the consistency on the sprites. The backpose is supposed to mime the frontpose, only with a backview, wich Wyverii's is doing.
;o
These are only examples I could remember off the top of my head, so there's most likely more; but front and back sprites do not always mirror each other in terms of positioning.
In most cases it seems that way mostly due to relatively neutral standing poses being sprited as just as neutral back poses.
I only made the backsprite the way I did because I wanted to show what is going on back there so, for instance, that a random battler who has never seen Elagune's sketches of Woodman has a general idea of what the whole thing looks like overall when they use it on the server.
Wyverii, a collab effort sounds nice to me, even though I've never done something of that sort.
Also, don't expect an animation. I most likely won't be doing one this time around. In Syclant's case, I was overzealous and went the whole 9000 yards and sprited anything I could think of in regards to him @_@. I might do one later on down the road for fun (the same with Revenankh) but no time soon anyway.
