I love the concept, the layout and the colours, but would strongly encourage you to straighten the tanks so they are vertical.
Levelling (i.e. true vertical and horizontal) has a significant impact on how we view an image - we are used to buildings (sans Tower of Pisa) to be vertical and it actually introduces a level of tension into the image. If this is intentional, (a technique called Dutch Tilt - a bastardization of the original Deutsch Tilt) then conventional wisdom suggests this should be at an angle >15deg - so like you mean it. This makes an image dynamic, aggressive and creates tension, especially when combined with close-up wide angle perspective. For example the following image of a racing car backed by a super yacht - the angle, combined with the closeness of the car and distortion from the short focal length express the aggressiveness of the vehicle.
