The single yellow flower wouldn't really be that spectacular or impressive, but the nice contrasting red flowers in the background along with the greenery makes it a bit more interesting, imo. I also find that unless I use manual focus, it's difficult to get the focus good unless the flower is centered, which makes me tend to take more centered photos. This does tend to take away from the ability to format the composition for more interest, so I have found that editing after the fact helps a lot. Nice macro shot.
This is actually called a Buttercup. They grow in Northern Canada in the province of Newfoundland. Very beautiful wild flower. Thats the first sign of spring when you see those bloom. Great pic!
thank you and have a very merry christmas!
