Well i took 8 stocks, and rendered 7. The background was the one that wasn't rendered [der]. SO i rendered the main focal, the "walker" to the left. I rendered the vehicle to the right. I rendered both characters above both of his shoulders. I also rendered both of the dying "EDF" soldiers at the end of both sides. I then edited all of the images so they flowed, and all had similar lighting. After that, i added a **** load of lighting to look like the light was bursting through the people. For the wallpaper and banner i added a lot of color filters to make everything blend, and for the wallpaper, i added a lot of star stocks on dodge to give it a fractal look. For the background of the wallpaper, i added an explosion stock on screen at low opacity.
Wow, that looks very good. If you hadn't said exactly what you did, I would have thought that you resized an existing image by the RF:G artists. The wallpaper is better than the banner, because it has cooler effects.
