Sigg1: Well, The first looks like you slapped a C4d on a black background... Sigg2: Looks like a clouds and a C4d
Light in #2 doesn't follow the stock's reflection at all. Keep in mind how the stock reflects light will make the rest of the light source come together. First needs more than a C4D mate.
#1: Well, The first looks like its alright, maybe needs a touch of C4D #2: I think that the light doesn't follow the stock.... Zack's face is too dark!!
two minute sigs aren't fun. You need more than a C4d for a background . Actually, c4d's are best used as effects, not slapped on as a background. They're harder than most to master. And the text? I'm sorry but making text see-through makes it look bad. For the second one, as the others said, the lighting needs to match. In the stock with zack, the light is coming from the right top cornerr, therefore, the sig must match that. Again, just posting a picture and a c4d isn't anything that's special. Anyone can do that. Start yourself with some tuts.
i like em both, except 2 things..... on the first sig, u should fix her pinky finger..... ont the second sig, the lighting is wrong....the light is behind him, yet theres light on the front of his face....
Sig 1 = I like it very much. The background reminds me Organization XIII's castle (or whatever is that) Sig 2 = It's ok, I like the black and the clouds in the background with the ray of sun
