Your adapter isn't hurting you. A 28mm f/2.8 lens is still a 28mm f/2.8 lens. While it might be thrilling to have the larger sensor of the full-frame (or medium format) camera, most of us aren't ready to plunk down $2500 for an EOS 5D Mk. II.

Just a heads-up, the m43 sensor will have low gain noise in general.
If you take a picture of bright blue sky in the middle of the day and look at the RAW, you can see noise in the sky even at ISO200, it's just how the format works (I have a GF1) and is nothing to worry about.
The shadow noise in your pic seems well controlled.
Granted the lighting wasn't spectacular in the room, but it wasn't terrible either. Theres a fairly bright halogen floor lamp behind me. If you do a 100% crop of that it looks like it was taken with a webcam or cell phone.
