This is my first time doing an entree for a challenge/contest this big. I hope to learn from everyone, and further develop my skills.

Description:
Those who live on/in the earth are its children and parasite. They grow stronger and stronger as their mother weaken, but they will never let the earth die as they were inseparable.

Progress:

This parasite is a tiny almost transparent little guy with a big appetite. It lives underground sapping away the earth's energy/magic, as more energy is eaten the stronger it becomes. It would continue to do so until it was ready for the next stage of its transformation.

Here the sketch for its next stage, the sentinel form, which is what I am going to focus on developing. In this stage, it basically forms a giant moving cocoon with the earth around it to protect itself from any potential threat.

After more exploration of the ideas and looking at reference, I decided to go with the ideas of 1 and 2. Creating a more anchored down cocoon/pupa stage with a slender tower-like silhouette or one with a heavier build. Mainly taking the idea from crabs or mantises.

These sketches are so beautiful! Are they traditional? I love your idea, it is so creative! Can't wait to see more! I love the second one on the last row of the sketch, but they all look so great!

Thank you, I kind of feeling good about the second design on the bottom as well. It most likely would be the one I am going to continue the concept with. Also, no, they are not done traditionally, it was just a texture brush.

Omg that first sketch is adorable lol Sketches wise I love the shapes of the shark looking thing in the top right on the lower page

School started again and stuffs got a bit of hectic, but I eventually got time to work on this a bit more. Still trying to stop myself from over detailing sketches, doesn't seem to be successful. Ended up spending way more times than I expect. But I think I finally got the idea I want.
Since the design itself was immobile and wasn't make to do much other than being intimidating and huge. There isn't much I could do to create a dynamic attacking pose and defending pose of some sort. So instead of just crushing people with its weight, I decided to go a bit off to the magical route. Since it saps magic out of the earth, at first I was thinking of a giant laser beam. However, later on, I kind of remember it is a geomancy bug that creat it's pupa/cocoon out of the earth. And that's basically what I did and it was the one that sticks to my mind the most.

Oh das a big boy

I like the perspective and scale of 3 but there isn't much in the way of showing the scale against something else. 1 is cool too

It's a complex scene what you're working on and I have a lot of respect for that. Hope you can finish before the deadline!
