Practicing with my flash

I decided i needed to practice with my flash.
My flash is a Nikon and my camera is Fuji, therefore the two are not dedicated together and i have had problems pairing the two.
These problems tend to make me shy away from using my flash and instead i stick with either natural light or getting the big guns out, which isn't always convenient, so i am now practicing with my flash.
Here are some examples of young Iris today.
