Hello Ashik,
First and foremost my apologies for not having commented on your pic, which has been viewed 173 times
by OPFers prior to this post of mine.
The theme you have selected to show us is a very rich, and to me personally a very interesting, one.
Now to your picture. In the bright of the bangladesh sun, the contrast range far exceeds the capabilities of digital sensors. So to bring these under control, either use GND filters, or do as I try to do sometimes,
shoot when the light is more manageable. bright sunlight also robs the saturation in your pictures.
early morning, late afternoons etc.
Direction of light is important. Just a suggestion, low late afternoon sun hitting the entrance of the temple would wash the whole surface with golden light and enhance your pic.
You allude to the 300 years old teracotta ( spelling! ) motifs, but we see just a glimpse of them. If that is the case, close in on those. Let us see them in their glory to fully appreciate them.
I am not good at wide angles ( not to say I am good at others ! ), but I prefer to get in close. I know it is a temple because you told us so. Make your picture show this to us without ambiguity.
I happened to be near a temple and not being able to shoot wide, I decided to concentrate on something I have found in Hindu temples all over...bells. here is my attempt to close into a subject, try to tame the harsh morning sun, and focus attention on one article in a Hindu temple.
These are just meant to illustrate what I have talked about above.
Hope this helps a little. Remember, I too am learning. Let's learn together.
Best.
