How can you say it's a language consisting of words from the main European languages, when you don't have any Slavic (e.g. Russian) words in it? Russian is the language spoken by most people in Europe (100 millions), and the other Slavic language are spoken all over Central Europe.
When the Central European countries become members of the EU would it be to embarrasing to have a "common European language", containing no words from the biggest language group in Europe!
The language lacks also some words from the smaller European languages (e.g. the Nordic, Baltic and Celtic languages).

But the idea of a common European language is very good, and I support your attemps to develop it - but there leaves much to be desired!
