The style I have chosen is reminiscent of official bionicle comic artwork, so hopefully it looks like it belongs!
I’ve emphasised Helryx as a battle-worn warrior, frail yet dangerous. The spindly limbs already present in TheUnderscoredDouble’s design are exaggerated, and some of the elements have been roughed up to make them appear aged. I’ve redesigned some parts that don’t translate particularly well, such as the hands, but on the whole I have tried to remain faithful to the spirit of the original design.
As an aside, mad respect for anybody who draws bionicles. It is so hard.
