That definitely is looking more realistic now. By the way, the barbell/dumbbell on the floor at the far right of your image is floating off the ground a bit.

I don't know anything about Dmap shadows but I'll see if I can help you research how to achieve softer shadows with it. Good time for me to learn as well. Keep in mind that a really good render usually takes time. I think cg movies can often times take over a day to render out just one frame.

Anyway, looks like you're off to a good start.
