I hope people read your title, otherwise I imagine you would get a few ones. Like the colors and the silhouette, It does look to me as if the image is oversharpened. Good work, maybe re-process if you are in the mood..
At first I scored this very low because I thought it was actually a sunset with tree. Only upon further and deeper study did I notice it is a bonsai tree with base, however, I still can't see in the photo the actual artificial light source. I can assume it is a bulb, but I prefer to see the actual light source. Others may have the first assumption I did though, so the subject matter may have been better differently chosen. I will up my score on this to reflect that it is not an actual sunset with tree.
I like this. I think I would like it better if there were so much "debris" (which looks a little bit like people's heads...and might be for all I know) under the tree. It is lit just enough for me to wonder what it is, but not enough for me to figure it out...so it is a distraction.
I am going to guess that this is a remake of one of the top photos from the original single light challenge. a backlit bonsai tree. nice photo, but no originality.
Beautifull artificial landscape.
Critique/suggestion for improvement: if the plant was closer to the camera, the corner would had looked like a mountain.
Now this is creative. I'm glad you put "artificial" in the title as I was about to tag another image with "single, artificial light source." Too many people used natural lighting, but this makes you stop and look. I like it.
