Frame it
I think that this piece needs to be framed and put on a wall, to show off the true beauty. Viewing it up close can only do the quality and the image harm. If you put it into a static situation, the brush strokes might give the piece more continuity.
Acrylic is a most difficult medium to work with and one false stroke can doom a piece, so you've done a good job here. What I'd suggest is with the image producing an appearance of breeze or wind about the scene, perhaps "comb" the greens in one direction or even have systematic breaks, where the stalks of vegetation are blown in different ways. This would also lead to colour changes.
The sea looks choppy, which means that the rocks look decent, though I would suggest that you make them a little darker, where they meet the path. Even with the spray over them, jagged edges of rock will show through and give you something to work with there.
With the proportions of the buildings and the trees, what have you got there? A church and a group of Sequoias? Perhaps thin the trees out and make the trunks less substantial there, for perspective. Would both buildings be the same colour, even down to the red of the roof tiles? Perhaps change that for a little more variation and throw in something to talk about with it.
