It was a big joy and honor your visit to our country and in our shops. You gave us the chance to show who we are and how we work. As you understand it is very important for us when someone with a trained eye like yours gives us new ideas and encourage us.
Well, let's see.
First sentence fine meaning-wise but somehow doesn't seem to flow. Tweak it around a bit and it'll be fine.
Second sentence, "how we work"
Third sentence "for a trained eye like yours to give us ...". Plus the tweaking for more flowing English.
That's my thoughts anyway.
Otherwise the meaning is correct.
