Its .tga, that means its a photoshop immage, so you have to download it, then open it with phototshop
PLease convert tga next time you take a screen, just open them in photoshop, and save as a jpeg or something
kinda boring, get some different doodads in there, also maybe a better angle, and also try n blend the gate in more with the surroundings, a random gate is kinda... random
