I'm not sure if you did the entier drawing in one day or if you did multiple part per day, however, I find your drawing pretty nice! (your line quality is clean and firm and we have a sense of space) If you want to help yourself, I would suggest that you aim at one specific thing during the challenge. Plan ahead what you are going to draw (the day before, before going to bed for example) For example during one of my inktober, I decided to use the list they provide, but I make the decision to integrate foxes in every drawing, the idea was to get better at drawing foxes. Even if it was just one fox doing something in correlation with the theme. You don't necessarely need to create on full illustration with rendering etc. You just need to workout a little bit every day grinding slowly but surely. (you will avoid frustrations, and burnout) Create bite size exercice that allow you to explore you drawing and a specific thing you want to improve on. As for the AT-AT, I would simply suggest that you figure out the perspective you want your drawing to be in first. Solving some of the problem ahead of drawing (you can use technics like ghosting your line just to figure out if your next line will be in the perspective for example) will tremendously help you in achieving your goal. And if you want still tu put your AT-AT on a solid ground, I would first recommand you to trace the surface the AT-AT is on instead of trying draw a full nature place. With one simple element as the ground you will already have a feeling of space and volumes. Hope this will help you. Don't hesitate to reach me on Artwods discord (shadlow) Cheers!
