i think you have some good potential.. but need to read a few more tutorials. that isnt a knock i promise. i hate to rate/grade anyone. since we all have to start somewhere
the second one is great if you didnt have that bright blue light and the first one doesnt seem to have depth or flow keep up the good work read some tuts
then tone down the blue light you can like paint black over it and overlay it or something to make it not so bright
snake sig = too dark Sasuke sig = Delete the scanline around sasuke and bring the blue abit down Assassins creed sig = very good but blur down his left arm (right arm towards us, that ugly thing )
