You provide a rough idea, wireframes are put together, you review them and give pointers, new wireframes are drawn, eventually you greenlight them, then the next stage is design draft, then redraft after input, then another draft, then another input etc.
Could you post some of the wireframes or their design drafts? Might be useful for you as well, because in my experience it is always a good idea to show and ask the actual users of a product the GUI before programming it, they might even like it 
I prefer to keep silence and then to start ringing all the bells at once.
