@Ikuru: to many rotated texels/ pixels on the surfaces. The more UV edges you can align to the U or V axis the more aligned pixels you will get on your 3d model and the cleaner the look. Rotated pixels work imo. only good on higher resolution textures, the lower it gets the more important it becomes to align UV edges.
For those that didn't see it, check out this recent thread for some great lowpoly art by RUX: https://polycount.com/discussion/231437/handpainting-normal-maps-pixel-by-pixel-100-photoshop-0-highpoly
I dig your epic pixels evilblah, and raise you some DUCKS D; Complete with a 'special' duck~ EDIT: I've noticed the .gif is being scaled down by a pixel or so here... : (
