Excellent work. Congratulations. The lighting created a nice mood and you had the camera fixed on a tripod for stable shots. I do think you will need to get a focus gear for your 100mm. I appreciate you tried to get the rack focus look with the ghost pipefish but you could've done it better with a real rack focus. It would've worked with a few other shots as well in your clip.
You may also want to consider rearranging the sequences to tell more of a story. Right now, it's just a collection of cool clips. Having a storyline gives a clip more life as it were.
Showing my ignorance.....What is Rack focus? And will it work for Ikelite, 5d mark ii with a manual focus port from Ike? I am interested in hearing more about this.
Thanks for the comments Drew. I appreciate it.
