This, Sir, is a completely realized and beautiful dio. Gloriously icky subject matter (don't wanna know what the giant floating brown objects are, if they aren't meant simply to be Barrels =D ), and every detail has been well-rendered. Love the Worm, the minis, all of it. 5/5!
Sweetness! My favorite part is the angled support pillars. Nicely done! I also like the use of repetition to make the large pipe feel industrialized, instead of being made up of a conglomerate of disparate elements. And the worm is good!
I think that you made the sewer waste the right way. The sewer worm is good looking. The architecture is great. I like the use of the Rahkshi heads. Screw the Bionicle haters, saying that it isn't Lego. I would like a bit more explanation here, and some of your other models, though.
Actually, I think you could do MORE detail... like on the ground, make it dilapidated instead of flat... but it's an awesome concept and build! Also, neon yellow studs would have done better for sewer.... waste.
Your detail here is simply spectacular. You have thought of a variety of unique building ideas, including the use of orange basketball rings and the green one by ones, which greatly enhance this creations realism. The worm is exceptional as well. Can't wait to see what you will create next.
I feel more sorry for the poor worm. Since humans aren't always around, it has to eat "other" things... I really do like the design, getting those pillars to blend in with the base at an angle is probably not a simple task.
Cool build, especially for a MocAthalon. You should try to take some lower and closer pics, though. Don't worry about cutting off the sides of the build. That way we have more of an immersed minifig's perspective, instead of looking at it from above like we're walking by in a show.
