I am new to deviantArt (just joined May 2012). For full credit disclosure, some backgrounds/textures for the Lords of Dyscrasia Fiction illustrations were enhanced with Photoshop brushes available from Obsidian Dawn ( www.obsidiandawn.com) which, in return for use, merely asks to be credited somewhere (the inside cover of the paperback also calls this out). Obsidiandawn is known on dA as "redheadstock".
Please see my author blog that has to date tracked my art, writings, and thoughts : sethlindberg.blogspot.com.
