My shop has been sooo slow lately, too! But I have noticed that on the days that I list/renew listings, my views and favorites go up, too. So I would say the key to getting business is to keep listing new stuff!
But you could also work on your tags. For the giraffe one (which i love, by the way ;), you should add some more tags like
giraffe print
giraffe painting
giraffe decoration
giraffe art
etc.
If you improve your tags, you should have some more views :)
As for inspiration, sometimes it's okay to just take a break from your shop for a day, then come back to it. Or, what I do is create lists of ideas (whether or not they are good :) and just run with it! Also, if you've ever had any custom orders/requests in the past, work on making those staples in your shop! If customers are asking for it, it must not be out there elsewhere!
Hope this helps! Good luck :)
