I’d tend to go with that because of the coloring - he MAY only be light-colored on top of the body (while having dark points on all under-edges, odd for a GS), which means no question, BelMal.
Yet, the ears are very big to me - GS - and the structure of the face looks a bit too bulky - GS.
He’s apparently a Mal, see photo below.
Beautiful good boy.
