To be honest, I'm incredibly pleased with the result. I spent half a day with the overall structure, and in general learning how to blender, and another half with actual sculpting. I made many mistakes and had to go back. I even messed-up in the end. This is too heavy I believe, and the topology is terrible because I wasn't constantly re-meshing (I wasn't paying much attention to the tutorial)
I don't know anything about this stuff, but I think if it's top heavy.You can have it three d printed With a honeycomb structure inside to reduce weight on the top
Edit also oh yeah good job, looks cool :]
