Panorama - Hamilton Italian Garden

I have been trying to create panoramic pictures from two or more images for long. The results were rather bad in my opinion. Today I have made one more attempt using Hugin. The original photos were taken last autumn in the Hamilton Gardens with the intention to make a panoramic view, although I had not had a tripod. I have also found that auto-exposure mode can ruin your panorama if your frames have different white balance or brightness.
