One of my picture that i have taken: Bungie.net : Halo 3 File Details Post any comments on this thread or on the link. Also tell me if i should make more picture's.
The picture isn't exactly original, but it is okay. However, you should embed pictures. easiest way to do it is to: 1) Create an account on photobucket/imageshack (or any other image hosting site) 2) Upload the picture to your File Share (this is 100% essential or you'll just get an embedded picture sayign "Pic not found") 3) Download the picture by viewing it in high-res 4) Re-upload it to photobucket or whatever (make sure you save the picture in a good place with a recognisable name when you DL it) 5) Once uploaded, copy the embed code (IMG code) and paste it in your post here. And then you're done! There is an easier way involving another site, but I don't remember the name of the site.
I'm thinking you got the wrong picture. The picture really isn't that great though. It's just a guy standing in front of the moon on Blackout.
I don't get the Dragonforce pic that you embeded, but as for the actual screenshot: Its ok... not very original. There isn't anything special about it, its just a Spartan sitting in front of the moon with an energy sword. If you added an effect, or did something with floating weapons, or really anything special, it might be better.
