The lack of any face detail makes the figure a little off-putting as a Bionicle one, but the GWP style doesn’t lend itself very well to that sort of thing without going the custom print route. I do like the detailing with the ingots, but the thighs seem quite bunched and the rest of the leg looks quite thin in comparison. Maybe he’s an Olympic cyclist
Overall though, excellent foray back into the world of LEGO building, and I hope to see more from you on the Boards.
