e n e Aiyo... Not ALL programs ka tools the same wan wad. Experiment bit larh. You can also use photoshop to do pixel because I always use PS to save wan, SAI can't save transparent bg (unless you buy it).
I just like SAI because I don't know... e v e it loads way faster than photoshop. <3
and I know most people who use SAI also nvr touch Acrylic, Crayon, Water 10, Water 9, Old Water etc XD but I modify and play all until....
