I did this as a gift for my Dragon some time ago after some less than shining behaviour from myself. Each of the various images around His portrait has meaning:

"The hands represent His love of massages, the d20 and sword for His love of tabletop gaming, Renaissance fairs and... well, swords. He adores Oriental culture and history, represented by His favourite food, sushi. The handcuffs symbolize His Dominance and involvement in the lifestyle, the thing that first brought us together. The NES and Playstation controllers are for His love of console gaming (not to mention that He is an avid PC gamer as well). He is a huge fan of Deadpool and DragonQuest and, last but not least, He sports a new model TRON lightdisc on His t-shirt, a nod to both His love of fun geeky t-shirts and the memory of watching the original for the first time with Him."

I figure I need better examples of the kind of work I can do. :P
