This one semi-followed both Pigglez ans Juggernaut's tuts, but since many of the words confused my feeble brain, I improvised. This one was in my recent screenshots, and the sig produced kinda...sucks ass. If anybody wants the stock, feel free to ask me.
Eh, the effects on the first one are ok, if there were less effects with toned down size, it'd be better, and bright green border = vomit. the second one is okay, kinda cool, 'xept the way his visor is contrasted, its kinda wierd.
i like the bright green border, thought a blue one probably would look better. the wisps are too back and forth flowy... if you look at juggy's "lock n load" sig, they are short and more confused. they look more like lightning.. so try using different filters. second one just doesnt realy work. i dont really get it.. i can see high ground on the bottom of the sig and what i think is a warthog/mongoose on the right, but the top part of the sig looks all weird. also the spartan looks like hes flying TOWARDS the vehicle.. try using a motion blur to make it look like its going away from it
