I also think it depends on what you are selling, in my art store (SuzyJaneB) I have about 110 items, all as well tagged and titled as I can get them, but I get more views and sales from my yarn shop, in which so far I have only managed to get up to about 30 items because my yarn is selling as fast as I can make it these days. I believe its because my yarn is very specific, people come to etsy with a standard set of search terms when they are looking for yarns, it all falls within a specific range. However, with art particularly, I think people are more likely to find you from browsing a wide and non specific search term. I have huge problems trying to come up with the tags and titles that I think will work for my art items, and I think when people are looking for art they also dont always have anything so specific - I mean who looks at their wall and thinks 'I want a picture there of a whimsy goddess sitting in a field holding a flower and painted in watercolours'. They browse general terms, makes it harder to find and harder to get views.
I wish I could get more non-etsy views, I dont get many from Google, and I cant figure out why yet... I do get views from my FB page though. Thats a help.
I think you should do prints for sure, and also your art would look really amazing on greeting cards or postcards too - I make those in my art shop too and they are easy and fun to make and you can sell them in sets as well as individually (more listing potential!). Also ACEO's attract a lot of collectors, and again your art would look fab on a business size card as a collectors card! They are also small and light and you can even offer free post on something like that, or even pop some in with your original art sold items as 'swag' - great publicity for you!
I love all your paintings :) Fantastic colours and design, and you have a unique shop and very recognisable work, I'm sure you will also sell a lot of prints! Go for it!
