Hi there.
Please excuse my English in this Bulgarian language club, but I cannot communicate in your Slovianski and I doubt you could understand Bulgarian.
I guess you are looking for some feedback from Bulgarian forummers.
Not being a linguist I cannot judge the language professionally, however to me it seems to be heavily influenced by Russian, Polish and to a lesser degree Serbian.
Going further, I think that Bulgarians without prior knowledge of either of these languages will have troubles with some of the vocabulary but even more importantly with the grammar. The concepts of instrumental and locative cases are completely irrelevant to modern Bulgarian and are likely to be unclear.

PS: It seems strange to me to use Anglicanisms such as "джерси" in a constructed Slavic language. Can you explain your choice?
