not a mark

Went in to the studio today with the aim of finishing this piece.After staring at it, mulling over ideas I still wasn't sure what to do to it.It seemed a bit plain, but then I liked it plain so I kept staring until about four hours had passed and I hadn't added a mark to it.Frustrating. But looking at it now its perhaps good that I didn't as I quite like it again,maybe it is finished after all?
