I must say as a beginner it is very hard to take macros. I find it hard to get the focus right and the very little breeze which disturbs the grass or flowers can be annoying. I think getting a tripod might help but it is little cumbersome.
You can find more macros I took other day here.
Check out my profile for more macro photography. I try to upload atleast one picture daily.
Any criticism or advice is appreciated.
