not generally a fan of smug mug sites, they never seem to look that nice
yours isn't too bad, though you really need to address the header picture, it doesn't look "integrated" and part of the site, looks more like a banner advert
as the site is a fixed with it shouldn't be too hard to make a header image that fits the width of the site and remove the black margins around it
the menu looks a bit dated and "clunky" too
if this is for a professional presence, not sure you need to have your gear listed, especially as you are using prosumer bodies that may actually lose your customers
I also don't like that the galleries takes you off site, if you can find a way to embed that into a page on your actual site that would give a better impression
not familiar with smug mug personally though so can't offer too much help in that regard, maybe there is a section on their forum about site designs with smug mug
as for it not working on your phone that really depends what phone it is, the on board browser might not support certain tech if its old, or it could be that your service provider is blocking it
I see you are using wordpress though, I would have a look at installing a better theme, you can get some really good ones for not much money at all
this is one I often link as an example of what is out there http://themeforest.net …nt-wordpress-theme/136628
there are free options too that would give you a much better base to work from too
just had a quick search and there are smug mug plugins for wordpress too for inserting galleries to your posts/pages http://wordpress.org/extend/plugins/wp-smugmug/
and another to add buy links as well, might be worth your while to take a look at those as well
