snake: the wand tool only works on contiguous part of the drawing on my version of PS.. for this, I think "color range"with no fuzziness works better.. otherwise, yes photoshop works , you 're right, just I don't feel to open PS just for this  (and I don't see the point of MS paint as I use promotion  ) , thx anyway..

Akira, when I remove unused colors nothing happens because all colors are still used, so it doesn't remove anything.. when I press remove duplicate colors, it really removes the color  from the palette, but all the pixels that indexed this color become black.. so actually Miascugh 's trick is the best,

Miascugh, thx, it works perfectly       I will stick to this method until I find -hear of - a faster one 

I'm really surprised there is not an  automatic way to do this action tho.. 

even though Mirre's background wasn't done at the good proportions , I don't think she is in as deep troubles as Snake..
Her different pictures already work pretty well together .. like they are from the same universe... But that's a different story with Snake's pictures...
I really can't wait to see the result... Good luck both of you!

wip of the day...   
I was pretty happy with it until I saw Ilkke 's post on PJ 
anyway.. I try to push myself to finish this piece.. I'm a bit lost with such a big resolution (for me)..


I still need to finish the chin, the hair (maybe some ears) and AA here and there..

C&C are very welcome.. (an edit would help too    )

what program do you use to animate your sprite, with photoshop i wouldnt know how to

just google "animation with photoshop" for exemple
you can use other programs like graphics gale, pro motion from cosmigo, even Flash could be used, I guess.. (use google again to know more about thes softs, you can also download a trial version..)
I m sure if you use the search button here you 'll find many answers to your question...
