This one is some thing special due to it located about 3 metre high under the ceiling, so I got perspective problem becuase of that.
After tried with focal range 50mm and 100 mm. it still too much to correct by software due to the hight, I start fit my 300mm f4 and move the camera on to the other side of the temple as far as it could and try to locate the picture at the end I got it and it quite good with perspective which I use a little correction on perspective via Photoshop.
Most of portrait painting in this temple will have name of person written, only 2 that not available, this one is one of no identification written to identify the person, I searching the information in many place and found out that most of people believe that by the clothing and the knife this should be and king whom reign this town during build up this temple.
