I'm currently working on original and altered character sprites. I'm currently working on Unmasked Reptile sprites for MK2. This is a simple copy-cut-paste-smudge but it looks good aside from that. I'm also using GIMP to ensure that the sprites run smoothly and are not choppy. These are the other sprites I intend to make soon:

All Ninjas Umasked
Re-invented Hornbuckle (not a pallete swap, there will be differences)
MK1, MK2, MK3 Tremor (Pallete Swaps)
MK1, MK2 Rain (Pallete Swaps)
MK1, MK2 Ermac (Pallete Swaps)
Sektor (Human)
Cyrax (Human)
New Cyborgs
White Ninja (MK1, 2, 3)
Smoke (MK1)
Gorbak and Durak
Buzzsaw (A work in progress)
New Tarkatans

These sprites are ones I will try to make eventually:
Hooded Noob
Reiko
Quan Chi (Altered Kano as seen in many fakes)
Unmasked Mileena and Kitana
Tanya (MK1, MK2, MK3)

I will update this thread as each set of sprites are complete. The first update will be Reptile unmasked stance sprites.

If anyone wants to add original sprites to this thread, please only post complete sets of sprites, or sprites that you intend to fully complete.

Any sprites posted in this thread are free to be used by anyone, however credit should be given where it is due. I will be using sprites from MK warehouse. I just wanted to give credit to the site ahead of time.
