These are variations on the same subject created using CorelDraw, PhotoPaint and Photoshop. The gondola is drawn in CorelDraw and then placed on the photo of the street (which was empty, I didnt remove any cars :))

The first one is entirely created in CorelDraw and PhotoPaint, using mesh tool, warp tool and some effects.
The second one is edited in Photoshop where i used several layers to achieve the reflection of the buildings on the wet street.
