Jurassic Park III Micro-Scale Boat And Spinosaurus

This is a Micro-Scale (although on a larger scale to my micro-scale aviary https://ideas.lego.com/projects/110685) representation of the boat in Jurassic Park III which is used by the characters to get near to the coast. The boat sinks, due to the Spinosaurus Aegyptiacus. There is a scene just before the boat sinks where the sail of the Spinosaurus pokes out of the water, just behind the boat, and this scene is the one I have recreated here. The blue colouring on the Spinosaurus' sail may look wrong, but it is accurate to the JPIII Spinosaurus                                                                                  -http://i.ytimg.com/vi/40C7RrAg5go/maxresdefault.jpg                                                                                  I have uesd cylindrical bricks to make the Spinosaurus' sail as it gives it a more natural and accurate look to it rather than using standard bricks, which would have made it look blocky.
