>>7973732>>7973790Going to go against the grain here and say you don't need to have specifically round pieces to make big tiddy bionicles. Pic related. I would go so far as to say you don't "need" any particular parts for any particular thing in general, since the limitations of the existing library of Lego pieces will always force you to opt for an abstraction of whatever it is you are trying to represent anyway. My advice to you is to take two identical pieces (or a single piece that would work as a bust) and try to figure out how they would look hanging off the chest of a humanoid robot. Once you find the parts you want and have a rough image, you need to determine connection points and how to integrate them into a torso. It doesn't have to be a completely custom one, but doing it from scratch will always looks better if you can help it.
If you are really lost on what to do without an instruction booklet, take a single interesting piece, and without any goal in mind, attach other pieces to it until you find a shape you like. Just practice with connections for a while until you start to see shapes or patterns that look like a part of a larger build.
