  6. Excellent Job Karen! Great Job on using enough color and it is neatly organized! I like how your picture is nicely done and easy to see. However, to improve you should have put another image, instead of just one. Another thing you could have done was to upload the video instead of just putting it as a link. Overall Great Job on your post!
