The 1st navi bar is very megamanish, I <3's it. Your second navibar is a bit messy though ó_ò. The screen dithering is pretty random, for dithering to look good it must form a uniform pattern (your dithering is a bit uneven and jagged). Another problem on < side, there are random gaps in the dithering (probably from copy pasting?). Well anyways good luck with this ^^.
