hey thats a good try but thats more blurring than anti aliasing, and its a little too much. i suggest going back to what you had and then using the magic wand to select, or just to do it manually and then blur edges but only a little.
and the gta part,

look at that and how the gta sign looks unpixely and has no double emboss. i suggest remake the title using the pricedown font, use a smooth text function, and instead of using the grey emboss, only use the black outline.
the IV looks fine but maybe a tiny little contrast might help.
and spaz I was just trying to help....
to make it better...
