Ivan,
I hope you plan on keeping the mark rough like it currently is. I like it a lot. That rough look doesn't transfer to the type very well. You will have some problems with legibility when the logo is made smaller because the mark is so big compaired to the type.
Nice work.
I've made this logo for the architectural workshop
"OBLO progect".
As for me I like the sign , and the customer agreed with it, but it seems to me that maybe something wrong with the letters...or anything else???
