This was something that I decided to do on Photoshop that surprisingly only took me 5 minutes to do. I might be making more soon :3 Click the pics to see the full versions. These are just simple backgrounds for people's computers. Something I did in an attempt to make these look more active :3 Tis an explosion of binary.
Not that impressive. You could just paint brush some colors on a black background and blur it up :\ Try adding some foreground or scenery to actually utilize the auras.
Not what I done, but that for me would take more time than what I done. No, because I'm not making a sig.
It's a good start, but they don't look finished. They are a bit too faded so they don't flow together like real auras do. Try making them a bit brighter and fill in some of the dead space with extra effects. Maybe add in backgrounds like Hayabusa said.
I'm not going to anyway. This was just made so I could use it as a simple background for my PC. I wasn't trying to make it realistic, it was just some quick thing I done on Photoshop. ---- To be seriously honest, I'm just sat here wondering why I even bother to post anything in this section...
Well if you put in your initial post what the purpose for your GFX is, then people can give different critique based around what you made it for. Don't be discouraged from posting here, we're just giving Cnc. It's simple opinion.
