Playing Card Pin Up

I've been trying for a long time now to get used to digital painting. I much prefer having a pencil of a paintbrush in my hand and all of the unpredictability that real life brings. But some digital paintings look so good and I want a piece of it so I did this, but why does it feel a little bit like cheating?
I'm still not sure if I like the results but it's always another tool to use.
