Your first photo is the most natural looking. A good HDR should make people go WOW so much detail. If it looks unnatural then people will just comment on the goofy part. Like in the second photo the bright green looks completely unnatural. The third photo looks good. The rest are not worth commenting on. But I will. In the first image you have nice detail in the shadow areas as well as the clouds in the sky. You have nice details in the snow covered grass. But in the last three images the grass is blown. The cement in the foreground looks wrong. They all look too contrasty. There are many ways to create an HDR image, you will find yours. I personally recommend Photomatix. It works for me.
