Conshelf 2 Posters and Art Prints

For this final piece to portfolio at least to the standard that I am willing to illustrate... I have tried to portray and emulate using modern technologies ~ the iconic camera style of previous generations of underwater photography... with 'classic black and white' and bold tones and contrast... I've decided to call it "One Foot In The Past"... It's quite unique... Can you spot anything unusual about the picture?
