The Shape Replications are looking good so far Martin. Remember to keep them as light as you can and make every attempt to curtail the urge to correct via multiple lines that collectively yield the “fuzzy” line (not that you are plagued with the issue by any means.)
The exercises are far more valuable than many tend to appreciate while in the trenches. It’s a great idea to flip or invert the page so as not to memorize the patterns–keeping the challenge fresh. Some even combine pages to yield a whole new collection of challenges.
