Opener here? 2 pics, cute af and super long nails

This chick on snapchat I matched on tinder with we had a video call few nights ago and since then she hasn't even opened my snapchat message but looks at my story and shit.. how could I send a takeaway I wanna ask her if she like lost interest or something? She seemed really shy and there were a few awkward moments but I did decent keeping the talk going.. but yea not sure what to say now I also have her number
