I think a lot of your photos are not 'etsy-ish' etsy/treasuries really love the white background so I would definitely try to take some like that. I think you should definitely keep the photos with models (to show size) but make it photo two
to be specific
http://www.etsy.com/listing/20472589/large-shoulder-bag-purse-nautical-coralfor this bag, all of your photos are either too dark or too bright, do you use any photo editing programs like photoshop? both of those are easily fixed even in free photo editing programs.
your photos are also really close in to the bag, in none of the five pictures can you see the entire bag (what do the corners look like? the back? the straps?)
your title is 'Large Shoulder Bag Purse Nautical Coral Fabric' the first three words in your title are the most important and yours are currently large, shoulder and bag. you should try something like 'blue nautical bag' and then add on things like 'blue nautical bag, large bag with cord straps'
the first few sentences of your description is what shows up in google searches so be sure to check that it describes your whole product (you can see how it shows up when you're uploading or editing the listing)
great job using back links to other items in your shop! make sure you use as many as you can :D
for your comment on florida tax, you can add that in on etsy. it will only charge buyers from florida. I don't remember how to do it but just look around under 'your account'
nobody is going to use 'free shipping' in their etsy search so I would change that to something else. there are a lot of articles out there for coming up with great tags. getting great tags takes a while and you have to keep changing them to find what brings buyers to you and for the season. you can use sites like craftopolis or etsy's shop stats to see what tags are bringing people to you. I like craftopolis more because it shows you what tags bring people to specific items.
