Hi Steve and welcome aboard!
It's always good to see someone else join up - I started midway through too and it really is a great learning experience.
I'm glad that you managed to find some inspiration for this, as you've read, I found this week a real struggle.
I like your take on the theme, it's definitely apple season at the moment, so a good fit for this week.
There's some lovely movement from the wind in the grass and I think I can actually make out some red apples on the tree. It would be nice to see the detail a bit closer though, so your idea of further cropping should really work.
I think I'd go a bit more extreme than your suggestion and make it a portrait crop to really put the tree as the main subject of the composition.
p.s. Don't worry that you've not had much feedback yet. I never look at anyone else's shot until I've got mine in for the week (usually Sunday evening) and I think a lot of the others do the same.
