It is important to upload your images at their full resolution. The georeferencing is very touchy and it looks like some of the points might be off which cause the whole model to be rotated strangely. The elevation values are pulled automatically from SRTM data so it is best to selected areas that are not disturbed by recent construction. The basemap georeferencing GCPs probably weren't close enough to the locations that they were associated with on the map. This too could be because of the reduced resolution of the input images. We don't generally recommend using a GoPro for mapping, especially with the stock lens.
