Hi Mironyc,
I do not speak the language personally, so this is far from an authoritative translation, and as with many translations there is probably a bit of room for interpretation and style -- but the most accurate translation I could achieve is: "Dominatus Sagittarium." Or in the case of a masterly mounted archer: "Dominatus Hippotoxota."
From what I can tell, "Graphicus" could be considered a wholly acceptable alternative to "Dominatus", but has its origins in painting, and therefore, perhaps, in my own opinion, has the potential to lend itself to a bit of confusion.
Anyhow, I hope this helps.
