Butterfly on Buddlea

An easy shot as the Buddlea is known as the butterfly bush. I couldn't help myself, as there were many butterflies to choose from. I think it a shame that the photo is so grainy. I'm not getting on with this Nikon coolpix very well and I can't wait to get my super fantastic camera fixed so I can play with photos more... depth of field etc I have just changed my computer and haven't put photoshop on yet and was wondering whether to or not. I do love the layers, histogram bar and the other gadgets but I wonder whether I can be bothered and just go for the more natural look or test out a free, simple adjustment program on line. Not sure.
