So, here's the mortal kombat avatars made by me, CnC please, i'm praticing with this effect, i guess that isn't my better...
========================










Extra:

program used?

also, i'm sorry but this looks like you grabbed a picture of each one and slapped it on a background with some added text

no offense but please put some more effort into your next works before uploading them here, ok?

if i knew what program you used i could try to find some tutorials to help you

I can found tutorials, i thought that i just used the wrong effect, or i missed the creativity... Anyway, your comment can help-me, Thx.
Also: i'm using Gimp.
