That really doesn't help very much. First Sig: - Needs better depth, add some foreground effects. The other effects are all kind of blurry. - Lighting could be better, darken some parts up. Second Sig: - Has a cool concept, good colors. - There are effects that are sharper than the focal, try to bring the focal point out more. - Depth could be improved. - I'd remove the text.
I am sorry for my false critism. Try cleaning up your effect's and making them more substancial with the focal's / tag itself. I also suggest not centering your focal's. I didnt think i needed to be -Repped for that though
Both sigs could use a solid light source. The effects of the first one look pretty good. I would remove the second face on the last sig and replace it with something else, just doesn't feel right.
Thanks for the great advice. I tried to do some stuff, how are these? -Made it smaller -Added a light source near top left -Fixed some blur -Darkend some parts -Made it smaller -Took away the second face -Added a bit more effect
