A bit worry and scary too why?
I switch off all the light in the office a avoid window reflection from the light in the office and it is damm dark! almost can't see anything oh... quickly set up my camera near the window and try find something for my camera to sit on . after few attempt still i got some reflection of the light from the window but i do some croping and touch up on the image of the reflection.
Try playing with the PS and this is the outcome of the result after touch up and put some affect on the photo.
