Very nice! Love your take on the Kaukau and the Mata torso. Her hooks look nice and mechanical and the sun has nice glowy feel to it. She’s looking really solid overall. What program did you use to draw this?
A few critiques:
I really dig how you did the claws though I think they would benefit from some pommels.
Her left foot looks a bit awkward. The ankle seems a bit too skinny.
The blobby background feels a bit out of place in contrast to the smooth, crisp lines of the Toa.
The white outline around Gali’s silhouette, while consistent with the other Toa in this series, looks awkward up against the very dark rock. Have you tried removing the outline and seeing what she would look like?
That cross hatching technique you used for the water looks good though it almost makes it look like ice. How about using more flowing lines, like this?
