#4- not great. Image looks flat... subject crowds the frame. Almost looks like it was taken by accident.
As for the others, again, you have compositional problems.
you're right, I try to learn the composition,
I know that other than no. 1, it's all in the center of the frame. I was told that in macro photography (especially flower), need to be put in the center. I was wrong. But isn't it in photo no. 1 , it's already comfirm to the rule of third?
Thanks
In the first one, the lamp is centered vertically in the frame, although it is offset to the right. Also, the thin strip of wall at the right isn't quite working, and the blob of something at the bottom detracts from the silhouette of the light. It leaves me wondering what other angle you could have chosen to either eliminate those distractions or else make them work for you.
