little cabin

This is a project were i used for the first time a HDRI or 360 photo. I took the photo my self. i know the cabin is still to small and i just couldnt get the proportions right. The bike is from blender swap

i was told on FB group that i shouldnt mix a real photo with blend model. But then i dont see the point of using a HDRI. Should i have just used the photo as a background a have built in blender the grasses and trees on a ANT landscape?
