More Elaborate Beach Theme?

Okay I asked this earlier and got good answers but I still want more so here is my question again:

Okay, so my bedroom is “beach/Hawaii” themed we r moving in2 a new house and I want to go more elaborate with my interior desgining (yes I am young if ur wondering I am 13 years old) In my old room I had a bed comforter that is Hawaiian flower printed and I have that Hawaiin skirt thing around the edge of my bed. I also have this fake sandcastle decortated with real sand , I bought this in Maine when I was there with my friend and her family in the summer, and I have real seashells I used 2 set out. What else can I do to go more elaborate with this theme, I also have decrotive pillows tht r bright warm colors and I have these bamboo curtains 4 my windows. what else can I do to go more elaborate with the theme what other decrotations can I use in my bedroom. Can u give my links to websites tht wouldd have anything? thanks.
