Ehum... returning to the art:
These are some great concepts and the I really enjoy the style in general. Nice pixeling with lots of character!
Some critique via edit:
At 1x and 2x res I was loosing a lot the the detail in the clothing so slight lightening of olive color.
The green cape on the leftmost guy wasn't coming through so i swapped around the colors and shadowed the cape.
Much increased saturation on the magic to make it magic and pop toward the otherwise gray colors.
Added shadowing on the wizard to imply glowing magic.
