a photo taken when some reflected light from some glass window fell on my floor, and i had just placed my coffee mug there.

I am an amature photographer without a good camera. If possible

please guide me....

Camera doesn't matter... you have an excellent eye. The image is well composed and executed and the softness actually enhances the mood here.

Please continue to share...

Nice composition. As Bill said, the camera doesn't matter. I used a 2 megapixel camera for work, taking pictures of test parts in the field. I was amazed at the quality of pictures the camera would take...
