Hello!
Honestly it didn't start badly and overall it's not that bad, it had some nice comps and tries out to keep it all consistent in terms of visual. However, the main weakness in the video was failing to build a proper atmosphere, scene selection was very split between the first and second part. There are some call backs to the more "romantic" part in the "action" part but it's so over the top with mecha, explosion and cute lolis that it really threw me off the romantic build up. There was another video that dealt better with this mix of action and drama and imo this one failed to do that.
On a technical point of view, I enjoyed the cookie cutter part at 47s and some of the static comps but the camera movements sometimes were a bit forceful or just a bit wrong in terms of camera management, like at 25s it doesn't look natural at all or at 1:10 where we have a zoom out then zoom in then going a bit on the right... It just looked a bit messy at times.
Overall it's far from being a terrible video, but in this context with it being in romance category, even though we tried to not be too strict on it, the video seemed a bit out of place. Keep it up man!
