Very nice indeed, the second two are my faves, i am not as sure about the onesided compasition of the first, but still a very nice picture, good to see that the macro wasn't just a passing phase, I hope you post more soon .
Funny thing with macros is it is so easy and so difficult to find something to take, what i find works is to take something out of the fridge and if you dont end up with a good shot leave it on the radiator for a week or so. My old art teacher was a great one for setting assignments, if it was difficut for anyone to find some material for the task he would just take one of the components, ie he would start with a house, if that was too difficult then a wall, then a window, etc untill he got to a stone, so no more excuses just pick the nearest thing . Go on make my day ...
