I don't think it's your prices or shipping costs, which seem pretty reasonable to me (I personally think some of your prices are low).
I think it's your titles, tags and the fact that you only have 10 listings that are the reason for the low views.
https://www.etsy.com/listing/113715843/lovelove-walrus?ref=shop_home_feat I noticed items that were recently listed (maybe relisted?) are still tagged for Valentine's Day. That's a wasted tag and can be replaced with the word anniversary or other love search term. You have a lot of single word tags that probably aren't being used in searches. They can be replaced with phrases such as silly love card, funny postcard, walrus card, etc. Your title "lovelove walrus" - do you ever see that in your search views? You can keep it in your title, but I'd also add other phrases that are more likely to be searched. Think like a buyer when creating titles and tags. If you were looking for a card like that, what would you type in the search box?
