I think you did a gret job with the colours and sharpness and being in right place – never managed to even get close to one of these so cant comment on the technical
couple things visually i think could help;
#1 – a vertical crop to remove distracting flower in background right side, hence bring the action :) to the centre of the frame
#3 lovely colours and crisp detail – could you have allowed a bit more space at bottom with more of the nice contrasting green against the yellow flower – if there was say 20% more to bottom in a square this might have been better
As i said i dont have any shots like this so only commenting on composition based on my visual ideas
