This is really well done. I love the coat of the lamp-head figure, all the subtle colors just in its back alone is really intriguing. Also really enjoy all the colors in the sky and how it goes from super saturated to more washed out to the bottom.
The main thing I would check is the child's anatomy, it seems a little off. Mainly the shoulders and neck. The kid's face probably should be hidden within part of the scarf, as it is now, it gives the illusion that the child has a really long neck.
I would also check the placement of the arm thats behind the Lamphead's head. For that arm to be where it is I feel like we need to see less of it, and it needs to be lower. Or - we need to see more of the child's back and shoulders. Right now it feels like its floating.
The origami bird second from the child looks like it needs a little more love. I feel like it lost the outline and crispness of its other birdy friends.
Really dig everything else about it though. Love the design of the lamp head. very unique and intriguing.
I'm really enjoying all your BotW drawings! I'm inspired to try my own series of each of the outfits, but it seems so daunting! I actually have a soft spot for the rubber outfit (except the helmet :3 ) It seems like the most modern looking with the sneakers and goth belts around the torso.
