UFO hovering above the trees behind our condo.

I went out to get the mail at the communal mailboxes. As I was going back to my place, I noticed an object hovering above the tree line. It was about 20 feet wide, eight feet tall. Had two bright lights on it. One of the lights was directed at me. The UFO was not moving. Just hovering rock steady. Made no noise at all. I watched it for about two minutes. It was about 220 feet away from me at an altitude of about 110 feet. The sky was perfectly clear.
I didn't have my phone/camera with me. But luckily, I am a digital artist. I stared at the UFO for about two minutes. I wanted to get all of the info about its shape so I could draw it later. I made a couple of images of the craft. But your terms are preventing me from submitting them.
Craft had a base that was about two feet thick. The two lights (like spot lights) were mounted on the base which was a dark brown color. The top of the craft had "bell curve" shape to it. White in color. There was one panel on the top shape that had a very shiny metallic shine to it. About 2/3 of the way up the metallic panel was a yellow light. There was a "haze" around the left side of the craft. The right side of the craft, which was facing the setting sun, was perfectly clear. No haze.
Stared at the craft for two minutes. I took my eyes off the craft just for a split second. When I looked back at it, it was gone.

Excellent eye sight.
