You did a mighty fine job with your close-up. There seems to be a little graininess in your shot so I'm assuming it was a low light situation and a higher ISO. Sometimes you just have to go for the shot and I believe you did well.
Im not normally a reptile person, but this just leapt off the screen - well almost!! Im glad it didnt for real as you wouldnt have seen me for dust! Great colour, and clarity too. Brilliant piece of work you have here - well done! Ann
