I can't speak for Mr Ploos, but he might have meant to be mindful of perspective. But he might check back in and expand on his thought.
Anyway, as to adding idyllic tone to the image, I would say you are zeroing in. I like the additional elements. I prefer the tree positioned as you have it, sort of enveloping the entry. And your flowers are also a nice addition.
I think it's vastly improved for mood and that mood you are looking to create. So you see the value of invention. You can improve on reality to amplify moods and feelings that you create in the viewers -- not to mention yourself having fun going through the setting you're planning and following your whim.
You filled the space much better. I think a comparison most people can understand is setting a table for Thanksgiving (or banquet for those outside the USA who don't celebrate that particular holiday of post-harvest bounty). Think of all the various dishes of food - turkey, stuffing, potatoes, yams with marshmallows, salad, various drinks, wonderful tablecloth, good china, candles, centerpiece, etc. And then add the people. That's not to say all that has to go in to every meal and every painting, but it could if the mood strikes you. And the point is that you are setting a table of sorts with each painting you construct. And it's all at your whim. Not all paintings are that big and full with subject matter, sometimes the paint itself is part of the offering -- as you put so much tasty color into it.
So you've definitely got the concept I was suggesting. So. . . GO PAT GO!!!!!!!!!!!!
