not every single pixel has to be placed by hand (i use copypasta and some line tools - never thicker than 1px) but auto-antialiasing that generates a ton of colors is NOT pixel art and a giant no-no =) it's just not pixel art, period =)) it's basically the only thing i look for when being critical. auto-antialiasing resulting in too much colors (without limiting the palette at the end which at least would be a compensation - see 16bit era!) will result in very low votes from my side >=) it's not about having no fun, it's about the fact that real pixel art needs a fuckton of passion and dedication and i couldn't even 25% finish my entry because it's not really possible in 1 hour - for me! i should maybe get a 'better' program than mspaint with some predefined dither patterns - i 'wasted' most of the time of the ohb removing the excess pixels at the edges of the sweater ^^
LONG STORY SHORT IF YOU WANT NO RULES HOST DRAW NOT PIXEL =) it's not mean, it's logical
as far as i can tell noone used auto-antialiasing in this ohb tho, probably also because i ranted so hard in irc and lowvoted everyone except 1 entry in the former ohb hahaha. in my already critical eyes, the entries of this ohb here are ok!
(yes, Midori's entry too, it uses manual antialiasing with manually chosen colors, GOOD BOY/GIRL, THAT'S HOW IT'S DONE <3)
