Nice photo, good colours, flower looks sharp but I think the fly has a little motion blur, your shutter speed might be a little too slow for the fly. I personally think photographing with natural light in shade is not ideal but thats just my opinion. The rest of the components of the photo look good to me, thanks for sharing
I agree with the blur on the bee, I should have taken with continuous shot. But it is impossible to take time to provide more light on the insect because they do not remain long at the same point, they fly away in a second.
