It's a good puzzle, but I think it would be better if you addressed what would happen in alternative lines of the puzzle. Just having the solution doesn't explain why it's the solution. Let me notate the position from Nxa5 to show what I mean.

You're right that I chose the engine's best line for the solution. I did explore those other lines. But the top line is the only line that White takes the Black Rook. I don't add alternative solutions because I assume most solvers will analyze the solution, anyway to discover different lines. As a rule, I don't add comments after moves because intermediate and advanced players will not require any clarification. Beginners can post comments with a question which I'm happy to reply to. Thanks for your suggestion, though.
