Looks like it could be good classic Flash art style with a little more practice! Lines are sketchy but not so sketchy that they lose that nostalgic charm. All I’d say is I’d recommend thinking in 3D when drawing shapes like this - you’ve got good shading, but the overall shapes look a little flat, and not how I reckon they’d be if this robot existed in 3D. Maybe some perspective practice for different shapes such as cubes, rectangular prisms, etc?

Keep drawing, you’ll be eligible to be scouted if you have at least 4 artworks!
