Mata Nui Rises

looks ok. though the area sorrounding the clouds looks like it was rushed into coloring. try using different blends of brown lightly and use a blender or a airbrush at a low opacity and it should look better. the clouds couldve had a bit of gray in em to make them have some volume to them.
The robot there couldve used some darker hues on his bottom to give more depth as well as a few highlights as to where the light was coming from. Hope my constructive critique helped out and keep up the artwork you'll improve as time goes on
