Wide Angle Distortion is a photo trick used when a object has been captured at a very close distance using wide-angled lens. It is often recommended to not use, and it can be avoided by taking a picture farther from the object; however, if you want to capture a more funny look or more background, wide angle distortion is something to try.
You certainly got the distortion. Even the second photo has some distortion. Try getting the camera fartehr back to eliminate it completely.
