In my humble, personal, take it for what it's worth opinion, yes...a little too much black. Your subject/focal point is getting a little lost. I think the composition that you were going for works, not being centered and falling on a 'third' line. But I think a tighter crop would help with making the subject the main focus of the image. There would still be some black or negative space to get that feel that you want, but it wouldn't be overwhelming.
