This is my version of my the crest of my WoW guild, Havoc (EU Hellscream server)
, themed to match the current end game raid, Blackrock Foundry.
The crest is normally a golden leafless tree on a blue background (which you can see by following the link above), but since we are a Horde guild, I found superimposing that image over a Horde crest has been a very popular look in the several iterations that came before this (which I haven't uploaded to dA as they were purely for our Facebook group banner, but I may share them in the future..).
Unlike previous photo-manipulations of mine that were constructed from stitched together pieces of various photographs, in this image I used images almost exclusively for texture, while creating the shapes myself. The only exceptions are the lava, which used sections of photo, and the myriad cracks running through the wall, which were brushes found here
Feel free to download this image for a desktop background (5120 x 2880 resolution, so it should fit most sizes of screens), providing the watermark is left intact, and the image is not modified or redistributed without my permission.
