HQ images are the backbone of a great presentation of your work. Each of these images created by the Homebyme community is a strong design statement and helps build the best possible understanding of the design concepts for everyone on the team. Better understanding leads to better results! Carefully study each image and note what really stands out for you. Look for composition, light and shadows and use of reflective surfaces. Then try to use those elements in your own images. You and your team will all benefit from the extra effort.
