Great for your first pixel art! the blue is a good color choice, but the yellow/green/black should be a bit more saturated.
Thank you for your comments. The black pixel should be the mic. but i think i should change the the black pixel to a little bit greyish color.
The black pixels are a little bothersome, and also I don't like the really fat stylus. But I like your palette and the way you did the buttons.
well done, face is funny... but the black pixels disturb me...
thank you
