Here are some of the worst Photoshop mistakes:

• Floating objects. This is when an object in the image appears to be floating in mid-air without any support. This can happen when the object is cut out from one image and pasted into another without taking into account the lighting and shadows.
• Distorted proportions. This is when the proportions of an object in the image are distorted, such as a person with a tiny head or a giant arm. This can happen when the object is resized without taking into account the rest of the image.
• Mismatched colors. This is when the colors in the image don’t match up, such as a person with skin that is a different color from their hands or a sky that is a different color from the clouds. This can happen when the image is edited without taking into account the overall color balance.
• Visible seams. This is when the seams where two images have been stitched together are visible. This can happen when the images are not aligned properly or when the edges are not blended smoothly.
• Blurry edges. This is when the edges of an object in the image are blurred. This can happen when the object is cut out from one image and pasted into another without taking into account the lighting and shadows.

Here are some additional mistakes:

• Over-editing. This is when the image has been edited so much that it looks fake. This can happen when the editor tries to make the image too perfect or when they use too many filters and effects.
• Lack of attention to detail. This is when the editor has not paid attention to small details, such as removing blemishes or fixing stray hairs. This can make the image look unprofessional.
• Unrealistic effects. This is when the editor has used effects that are not realistic, such as making someone look like they have no pores or giving them perfect teeth. This can make the image look fake.
