Andrey did the good job about the logo. He designed a set of logo for us in different color and various version (ai. png and so on). So we already used all of them now we do like it a lot.
Besides, Andrey is so nice when we asked him to change the color design of business even after he had finished all of the work.
I recommend him be your designer and wish Andrey can satisfy you just like he did for us.
