.......This sometimes gets me into a state of panic as I am a person who doesnt like too much change :P But its always worth it in the end, and I can usually once again find my way around the shop without too much hassle :-)
The enlarging of the sell signs are a really good idea, they look more professional, show more detail so are easier on the eye.
Using a nice plain background thats carried through with all the pictures make for a more uniform, uncluttered look and we find having only two rows of pictures in height make such a difference and by placing a large display photo in between every so often to break it up.
There really is nothing worse than going into a shop and wondering where to start, seeing just a mass of sell signs scattered randomly all over the place, most people will only leave very quickly.
Take a look and see what you think :-)
