The blending in this is phenomanal. Although it takes away from the render a bit, because i could barely see the render when just scanning over the piece, black lines are complimenting it well, and the text is in a nice position but hard to read. I think the render looks slightly oversharpened, needs toning down a bit. Your getting good with this style, the only thing it doesn't have is depth, some more gaussian blur around the render would help with that, along with playing around with the dodge/burn tool, good luck.
