the front roof edge forward say 40mm in front off the wood would protect it from drips also bottom 1/2-2/3 off the timbers cut back at 45% or sharper
would also put the front cross beam behind the legs and perhaps 38x63mm cls as the load and span is quite small as this would give you 2 or 3inches extra height
but not a criticism in any way just suggestions for less head bashing and arm stretching
