Google images really. I would type in a random string of keywords like Shadowrun, Cyberpunk, Male, Female, Decker, Rigger, Sniper, Elf, Modern, Cyborg, Fantasy, Dark, Soldier, Mercenary, Assassin, Magic, Magic Sword, Etc, and put the word 'Art' or 'Concept Art' at the end of the string and browse from there until I found something that matched up to what I had in my head.
Finding an image for Kynos might be next to impossible but I'm still trying.
