I would have to say the 2 and 3 stick out for me. Although what bothers me about all of them is the dust you must have on your sensor. There seem to be a lot of little black dots plaqueing your pictures here. I think the lighting could be a bit better as well. Nevertheless, for your first time, good stuff here. Better that what I could have done for the 1st time.
If your question is: which one of these is your favourite, I would say 1 and 5. And congrats on catching the "droplet-virus", this forum suffers from malarialike inflictions of "the disease" occasionally, let's see how many will get "infected" this time by your photos .
But all your photos need some more PP work, mostly to clone out the sensor dust, but also to further work on brightness and contrasts.
But all in all you did better in your first attempt than I did when I was first infected with the droplet-disease!!! I should get myself infected again, what with my tools to work on this kind of stop-motion close-up photography having improved a lot since the last time I tried (some three years ago).
