Here are two signatures that Ive made, and I've really just started GFXs so i know they suck. But I want to see how i can improve them. like what more could i do? Lots of comments and constructive critisisms are needed and welcomed. Edit: Also my first sigs
I would use text that goes with the rest of the image. Blend the render a little bit the BG in some parts. Try to get a flow going with the colors throughout the image.
GJ on your first sigs. You could improve the text. Try text that doesnt look so styley. Just plain text so it doesnt take the focal away. Read tutorials
the answers to your problems and more are in the tutorial section......looking into some of those will give you a deeper understanding for the criticism thats being given...However, so as not to avoid what has been asked.... For sig 1 render could use some attention...seems as if the background is where most of your attention went and the render was put in last ...try smudging, adding light source(s), blends....anything to improve depth and contrast Sig 2 Same things apply...although in my opinion this is the best of the two. It seems that this is a good starting point for you to add the things I talked about previously......all things considered, good job....
for starters: DON'T USE TEXT AND THE BORDER UNLESS YOU ARE REALLY SURE THAT BOTH ARE ADDING TO THE CONCEPT OR THE TAG ITSELF
