Hello, Aljoscha. I wanted to leave a critique for you, since I am a great fan of your landscape photography. Let's start with the overall image. The colors are perfectly chosen and they do fit to the title very well. "Morning sun", that's what I expect when I hear the title. All the impressions of that magical day in autumn you experienced can be seen here very well. The atmosphere is simply enchanting and enables the watcher to dream. I especially like that you placed the "main" tree a bit left from the middle and set the focus on that tree. I love that the whole scene is sharp, too much depth of field would destroy the will to search the whole image for more details. I have only got one point of critique, now that I see the image being uploaded (I did not see it when you let me see the picture before uploading.. ): Only the left half of the picture is really illuminated. The right part seems to be swallowed by darkness. That may not be a point of hard critique, though. This part makes the composition dramatic, but maybe it would have been better if the sunlight somehow also hit some spots "in the dark". I know it's hard to accomplish, because you cannot guide the sun to specific points.
All in all, I really love the picture. I already told you that the colors are amazing and emphasize the overall atmosphere of warmth and coziness, although it may have been a cold morning. Keep up the great work, Joschi!
