Matt this one seems a bit overdone to me... one trick you could try with HDR is to play with the following (assuming you are using Photoshop)
1) Make the HDR
2) Copy the HDR image on top of the the best exposed original as a new layer
Here you have a few options and you can experiment for different effects
1) Apply a blending mode from the HDR layer to the Non-HDR layer like overlay, lighten, darken or multiply - see if you like it
2) Adust the opacity to tone down the HDR effect while still getting color and detail in places that are lacking in the non-HDR layer.
3) Create a layer mask and make it all black (so you only see the original image) then use a paint brush with lower opacity (like 10-20%) and slowly paint white on the mask to bring out the HDR areas on top of the original.
If these don't make sense send me an email and I can clarify better... These should help keep the good parts of the HDR while maintaining a more natural photo.
