Originality: 7 Ah yes, "The r ape of the natural world," as Ian Malcom said in Jurassic Park's film adaptation. The ship is a bit of a cliche though. Techniques: 8 That Rock with the joint piece is really cool and it puts a big twist on rockwork, I wish you would have done that with the otherone. The grounds seem bare, but I suppose the less stuff you have to destroy, the better the sell will be. I'm not too pleased to see "Gary" only because he is the same basic build as the one made be the LEGO Designer who made the set. Make a hermit crab with those shell pieces, I'm sure it'd look cool. Presentation: 5 Easiest points to win ever. Total: 20/25 Good job.
Originality: 7.5/10. Everything is cohesive, its obviously an ocean scene, and all the colors fit together smoothly. The sunken pirate ship has been done many times before, but the realtor coming to check the property helps to make up for that.
Techniques: 9/10. I like the way you fastened the flippers to the ground, and using the racket joint for the rockwork is ingenious. Also, making the coral out of minifig arms is a great idea. My only quibble would be that the seaweed is rather repetitive and the dark tan rockwork is boring compared to the rest of the build.
Presentation: 4.5/5. You have the required links to the Contest Group, and the black border lends a distinguished air to it. Some of the pictures are just a little too close and out of focus, but despite that, this is still a great build!
Looks great! I can tell you that this is very realistic with confidence, because, well, I live where I live! This is exactly how the ocean floor looks, mostly sand with pockets of coral here and there. So great job in realism, and good luck in the contest!
