PLEASE ADD SHADING. I see too many packs like this where they copy the default and make it bland and flat looking, and the thing is that the default blocks are the only ones that tessellate well. Either put time into your pack and present something original or your just another guy who hopped on the 'easy pack' bandwagon.
P.S. Don't add all the hues and distort the pics like GHOSTCADE stated.
What do you mean to add the shading, even few hue (Isn't that hue. But I used the GIMP in color curves and balance), copied the default (nah, isn't that default but I've make it) and distortion? Actually, the GIMP and RealWorld Paint (freeware paint program)have/haven't few distortion but there are the few vignetting, layer, color balance, colorize and other ones.
(Sorry about the foreign English like that. Because I lived in Saudi Arabia)
