Its simply stunning! the use of a very limited number of colors and effective lighting has made this photo-manipulation extremely unique and eye catching.
Going from top to bottom, the clouds that have been used are very well placed and the color have been well matched with the sun shining from the right. The tree, as I see it is the most unique part of this artwork and it has been compiled perfectly with extremely beautiful reflections on the lake.
The background has been well created and the partial view of the mountains have given the whole artwork some depth however I do think that the trees on the left are a bit too detailed and highlighted grabbing the viewers eyes away from the main element.
As a whole, this artwork has been created with amazing skills and has a very unique artistic touch to it.
