Water Drop with 105 mm 2.8 macro

I wanted to post a picture that I took with my new to me used 105 mm 2.8 lense.  Some people were on this forum were nice enough to discuss some basic features of the 105 when I first got it, so I thought that I would post a picture.  I set my backdrop tripods up with the cross member and a dropper attached to it.  The shutter speed is 2500 and the F stop is 20.  The SB800 flash is set to remote and I am using commander mode with no on cammera flash.  The E1 flash sync is set to 1/320 s (Auto FP).  This allows the faster 2500 shutter speed with the SB800.

Please comment or give suggestions.  I am new to this type of photography and want to learn more about it.
