MacroPhotography - White Flowers

As a beginner and exploring DSLR camera, I thought of not using Auto feature but directly diving into Manual. It took some time as well as the number of clicks to get these two pictures. Though they are not best, but I think its good enough to get started.

Though there is not much difference in these two photos, but if look closely you will see the 2nd image is a bit sharper than the first, I think the main reason is the ISO.
