I'm a bit late to the party, but I checked your website from my mobile (5-years-old LG) and it's lovely.
The only thing I might wish - but I always wish for that - is an option to change the font (mostly enlarge it), without automatically enlarging the current page I'm looking at.
It also takes some seconds longer to load the website which I'm inclined to blame on the fact that I use AdBlockerPlus.
Hope this is helpful
