Well I wouldn't say the bg is that realistic, just good old dither.. To me personally dithering is much easier than any other aspects of pixelart.. Especially after working in full color media and then returning to pixels :D
Apology accepted ;)
Yeah the stamp is already up :D
As for 'allegations' like that thing Vital said, I'm not even gonna comment. For anyone who doesn't believe I made so-or-so - come up with some arguments better that just your own intuition & guesses... Otherwise, you're just wastin' time.
Nice background
