i like some things like lets start off with no.1
1) The black and white is a good plus but the text is very bad search for some diffrenet ones cause this looks really bad but the effectes in the background is bery nice i rate it a 8.5 just get some new fonts!
also remove border makes it look newbish
2) This is a better sig but the font doesnt match the strong blackish greyish and lime green background i really like the render but yu should add some effect to his body just a little so it doesnt look like you just did the background den sloppy put lashley on i give it 9/10
3)The 3rd one was probably the best it had great effects and i like the faded pic in tha back of him and den the render of him with the arms pose but still nawt like the text you shouldve use the same font but in a redish brownish colour cause the silver makes it look weird 9.8/10
