Another signature, took alot of suggestions and tryed my best with my knowledge of everything ( which isnt much, but is growing) and this is what I got this time.
Looks like you're improving. The text still doesn't fit. Try choosing neater fonts and using a color from the image as the color for your text. Oh, and what is that glare behind the red ODST? In your next sig, try playing around with C4Ds.
C4D (Cinema 4d) is basically renders...at least I think so. Others can probably explain much better than I. IMO you need to edit out the spartans over the planet, and get higher resolution renders. Also, that large glare, light thing over the red spartan seems unnecessary, and perhaps you should move the 2 spartans more together to one side. Also, text should be a subtle element, and clean, simple fonts generally look very good. For yours, I would move it to be out of the middle....change the colour, lower saturation for sure.
I thought C4Ds were those abstract 3d looking renders which people generally use alongside/wrap around the regular render images used in a sig, stuff like the first row of this Google image search. I've no idea how they differ in terms of technicalities and using them in programs like PS, but I'm pretty sure C4Ds means specifically renders like that, rather than just renders in general.
Yeh. A c4d is basically a render and when placed correctly it adds flow and overall good looks to the image. Something like the splatters on the right side of Emile in my sig, or the lines that appear to be emanating from him.
ok c4d stands for cinema 4-d its the program that makes these you can find them on special graphic websites. but you need to be signed up so its best to just download many in a pack from like deviantart.com... don't worry about c4d's right now. just focus on basic lighting, coloring techniques, text, and placement click this and use those resources and what not. all very helpful ALSO YOUR IMPROVING IMMENSELY!! still gotta do something else with that text.. and also try sifting around the intranets for better pictures (stocks) to use for your siggys
