Welcome back! It's good to see you coming back to this, especially after your much-deserved shift into your personal projects.
I have to say, there is a very dramatic difference between your previous pages for this project and the new ones, a difference I really enjoy. The previous pages were very vibrant, bright, and colorful, much like your old work. That was good for the beginning of the story, I think, because it conveyed the richness and diversity of Mata Nui as a setting, as well as its characters.
This time around, though, I really enjoy the way you're using lighting and contrast. The colors are a little more muted because of the shading, but it contributes a very cinematic effect to these pages, which is really awesome. I especially love page 25, the last two panels of page 30, and page 31, which make excellent use of sunlight and atmosphere.
As always, I really enjoy the way you draw BIONICLE characters. It really feels like you've struck a happy medium between the biological and the mechanical aspects of the characters, and you have an excellent sense for reimagining the appearances of the Toa and Matoran, making them unique and visually exciting while also keeping them recognizable.
I do hope you're able to keep going with this, no matter how long it takes or how many breaks come along the way (my selfish half would also be ecstatic for a potential return to Nova Orbis, though that's entirely up to you). Keep up the good work, and good luck with all of your other projects!
