For me (though I'm far from an expert, still learning lots), I think the composition would be better with the "gardener" either in the frame or out of it, not halfway as you've framed it here.
The red channel is significantly blown, causing the "nuclear" colors in the flowers themselves. This is often a difficulty for me when shooting flowers or other heavily saturated colors.
Apart from those two issues, I do like the concept. The three regions of the photo differ in both texture and color, which is nice, and the wheelbarrow adds some valuable interest to the foreground.
