I am wondering if you clarify if wave 5 is really impulsive since it looks more like a zigzag. Taking a closer look at wave 1 and 3 also appear to be zigzags. internal 5 waves do not look clear enough. hence I am suspecting that may be what you have is either double or triple zigzags depending on who you label them.
Though overall I think you are correct that a retracement is probably in progress.
