This is an artwork I made of Kaylan, my Geek Sim (though he's not much of a geek).
He has the Rocker career path though he has a higher Art skill level. :D
I made this in Adobe Photoshop using mostly the Pen Tool and some Brushes and gaussian blur. As you can see I've added a few items that can be found in the game XD Which can also be found in my Sim's home.
