Of the two images, I prefer this one. I think the greater depth of field suits the subject better. But "de gustibus, non est disputatem" (you cannot argue about taste). As far as both images are concerned, I think your tests have worked.
I also prefer this one of the two. It's crisper. Richer. I almost hear the faint, dying sound of a piano chord....
Personally, I think it would be stronger without the "Boston" script center stage. Maybe move up or down the keyboard to eliminate this logo?
Thank you for the comments. This was more of a test subject for the Tessar, than anything else. But surpsiringly I like how the pictures cam out. Later I will try the shot again, without the Logo and see how it comes out.
