Looks like you added blocking that sort of looks like a gable end ladder, but it doesn't extend to the last rafter?
Is the last rafter just supported by the top and bottom fascia board?
How much snow will that thing see?
Edit: I found it, you said 3-5 feet of snow accumulation? You should probably better support those end pieces. Sometimes the snow "curls" at ends of buildings and gets pretty heavy. Also, everything sags with time.
If you look at how buildings are made, the framing pieces are always ALWAYS stacked in a way that does not rely on the fasteners (screws/nails) to hold any load (with a few exceptions such as joist hangers).
With almost all framing, if you could magically make all the fasteners disappear, the house would still stand. This is done because wood is so shitty, it gets mushy or dries and splits, etc. But if it's stacked and all the ends are captive, then that doesn't matter so much.
