First HDR attempt

Hi guys thanks for looking. My first HDR attempt here, not sure if appropriate or overdone...but without HDR i was unable to get the detail of the abandoned room alongside the detail of the outdoors.
Shot through the window from outside on a windowsill!
Any feedback is much appreciated!
