Hi L4xord! I love that you are practicing with rendering, but sometimes we get so caught up in making the shadows blend together that it smooths out the entire form. It can be very important to show how the object exists in space with these precise shadows, especially for someone interested in industrial design. Maybe you can combine perspective and shadow studies by using flat or faceted shading. By doing this, you will begin to see the planes of an object, which helps to both define it and make it easier to place in a perspective study. This is just a really basic example of what I mean: Try seeing objects the same way as the vase on the right appears.
