Huh. At 100% zoom, it doesn't look at all pixelated to me (what are you using to zoom in? your version does indeed look terrible) and the version I uploaded certainly wasn't digitally enlarged. You have circled light reflections in the water droplet. I don't see it, but I'll just shrug my shoulders and move on.
I know what it is reflecting, but the over-sharpening is very apparent in that spot.
I just viewed it at 100% size in the browser window and in Photoshop. Let me try to demonstrate a better example that's actually pixelly instead of just looking oversharpened.
What resolution/size is your monitor? It might be hiding these issues from you.
