That's Cyrax, not Sektor.

oh crap my bad i got confused

I don't like it; no division between where his "mouth-piece" ends and eyes begin, the points for his eyes are not even, the grey on both sides of his head is uneven, the "shading" (spray paint style) is out of the line in the yellow part, his mask design's not even, his eyes aren't the same size, the spray paint on his grey head part is useless and a poor attempt at shading... I'd say more, but I have to go to class. In any case, I don't like it.
