Beautiful presentation aside, this creation is definitely in the top three. Beautiful composition, texturing, and an intriguing dual-level structure make this entry my personal favorite. Minifigs: 24/25. Build: 24/25. Creativity: 50/50. Overall: 98/100. Well done!
The way Shelob's legs come out is really nice, and you presentation is as good as your build. May I ask what program(s) you use? Also, are those spider webs in the first picture real/from another image, or did you make them digitally? Great job. Good luck in the competition, although it's not like you need it.
