I like the look of the new site and I think it may well look a little GILLISH, although we can never know for sure. I'm inclined to say it does. But to be sure, you could change the colours to those more associated with the 1910s-1920s, especially as regarding print graphics.
For gawd's sake don't quote wikipedia as you have done. Read Wikipedia by all means, interpret what it says (aka understand it) and then rewrite it in your own words. For example, I might say "Gill was inspired by Johnston's work for the London Underground to create the most legible alphabet yet". Or "Gill found his inspiration in the work of Johnstone, most known for his typeface for the London Underground".
