I beg you to renew the Raw Class. The new material is completely overhauled and updated, and the new Flow Chart is miles better than the old one. And as a previous participant, it's very cheap for you.
Yeah, the big thing that's missing from your photo, that's present in the others, is the depth of field blur.
Do you have another photo of your own, with a better blurred background, that we can work with?
Can you explain the problem a bit further?
Do you have different cameras from each other?
And are they the same cameras you've always used? Have you synced successfully in the past?
It's not fabulous, but if it's the best you have, you can definitely use it.
When it comes to sharpening, you might have to mask it off the tree, because it might grab all the attention.
The reason I ask is that the pink flowers are completely unprintable. WAAAAY too vivid.
For the background, I'd add a green Solid Color layer, reduce its opacity to taste, then very carefully mask.
