Nice work! It's cool to see you putting in the mileage - it takes a lot of patience to create 1 value scale, let alone 4, and I can see the improvement as you move down the page. Based on the visible pencil strokes and the way that some of your shading falls outside the lines, it does seem like you need to slow down a little bit and work on your control. Stan used the metaphor of shading like a robot in his video, which is how I like to think of it: focus on keeping your pencil pressure and the direction of your lines as consistent as possible, making the same repetitive movement over and over again, just shifting the location of your pencil slightly with each stoke. Don't be afraid to build up tone in layers - make 3, 4, 5, or even 6+ passes if you have to.

Sexy Line weight. Don't see anything wrong

These are wonderful! Both of these buildings are perfect for this project. I appreciate your little sketches and the colors are cool. The only adjustment I would make is a small one- The ellipse for the ground on the first building seems a bit too narrow. Widen it to make it match the perspective of the building. I also added a cast shadow to the ground to make it feel more cohesive. Overall, great work!

Great job! Very nice drawings with very good 3D effect and dynamic gesture!

This ant is AWESOME!! Great work, love the shape design and simplification. Careful of the cross contours on the legs and antennae, they get a little flat toward the edges of the contour, make sure to WRAP cross contours most dramatically where the contour disappears to the other side. Keep it up!
