#7 I understand the problems that occur when shooting through a safety glass, but you could try different WB to change the appearance but can't say I hate how this one look though
#6 What are those black streaks in the picture
#5 I feel indifferent about this one
#4 It looks as if there is a "two window" effect around the anemone (which is actually the other side of the aquarium) which I like; don't like how you had to use the high ISO though
#3 Is my favorite. Very contrasty. I like how the jelly fish looks to be sleeping in the bed of seaweed. Again the high ISO is noticeable but not as bad as #4
#2 I like the angle you took it at
#1 Feel indifferent about this one
Overall IMO pretty good job
