Ok...great to see where you are at. For the next one, please try something for me. Try mapping out the line drawings with both images upside down. This is a trick that tends to get your mind to let go of the 'what it is" and lets you focus on the shapes themselves. Don't worry about details...the main thing to focus on is the big positive and negative shapes.
Google Bargue Drawings. You will see how shapes are mapped out, not just around the objects...but the light and dark patterns in the piece. For example the landscape original is more about the shapes of the trees against the sky, than perhaps the outer contour of each tree. Look for value shapes more than looking for what the image is. The values and their shapes fit together kind of like a puzzle with sharp and soft edges.
Lastly, I know you are spending more time looking at your image than moving your eyes back and forth between them. When artists do that they end up with figures that are bigger or big shapes going unseen. You can totally do this...we just need to slow you down a little and look at the original, and while remembering a shape with your mind, put the shape down in your study. Then immediately look back again and check what you did. Your eyes should be looking back and forth every 4 seconds or so...not every 10 or 20. Keep your eyes moving. It will improve your accuracy and cause you to spend more time looking at the original, in order to get information from it to put down in yours.
Keep it up.
