I overexposed the photo to achieve that dreamy effect.
Then use dodge & burn to highlight or darken parts of the photo
I am glad you like it!

In general, you should try to avoid editing your photos, whether in camera or with some editing software on a computer. Being a good photographer also means being able to take good shots without having to edit afterwards. We understand that enhancing pictures after the fact has a long tradition in photography and thus we allow for certain digital darkroom techniques, which is readily available in most photo handling software today. As a general rule, you are allowed to all adjustments which act on the whole picture and on exactly one picture (a.k.a. non selective editing). This includes:
- 6.1.: Level
- 6.2.: Curves
- 6.3.: Hue
- 6.4.: Saturation
- 6.5.: Color adjustments/shifting
- 6.6.: Brightness
- 6.7.: Contrast
- 6.8.: Gaussian blur
- 6.9.: Noise reduction
- 6.10.: Sharpness
- 6.11.: Crop and rotate
- 6.12.: Lens correction
- 6.13.: Camera raw editing
- 6.14.: Healing brush to remove dust and scratches from a scan or speckles from dust on your camera's sensor
- 6.15.: Duplicated layers
- 6.16.: Layer blending modes
- 6.17.: Transform your photo into HDR
- 6.18.: Make panoramas
- 6.28.: Use dodge and burn

As long as dodge & burn is OK to use according to rules & guidelines i am free to use it.
