The 6 Guidelines to better pictures.
1. Simlicity

The picture on the left shows off simplicity better than the picture on the right because it is a close up of the object, hence making it more appealing.
2. Rule of Thirds

The picture on the left uses the rule of thirds better than the picture on the right because it has the object on the uppermost right corner giving it a better angle and lighting.
3. Lines

The picture on the right shows the lines of the picture better because they're not just up and down but also horizontally and the contrast of color just gives the picture more appeal.
4. Balance

The picture on the left shows off the balance guideline better because it's symmetrical while the picture on the right is just clustered and loaded with detail.
5. Framing


The picture on the left shows off the framing guideline better because the desk and dresser are within the frame of the picture.
6. Avoiding Mergers


The picture on the right doesnt' have any merging because it has a contrast of colors which prevent the object from merging with other objects in the picture.
