jobel - I am animator too
For animations on pixel art I usually charge $30 for every 6 frames of animation, and if more than one, I charge an additional $10 for each new animation instead of $30 for each animation.
So would be: $30 for one new animation (with 6 frames) and + $10 for additional animations (6 frames each animation)
But we can always negotiate
The payment must be made via paypal
