Personally I didn't hear anything wrong with it. That middle section of 4 based on G ... it provided a tension that needed to be resolved but you actually did it in a decent manner. It resolved nicely by returning to the original progression of D G A.

In no way did that middle section sound like a key change to me. You resolved it. You could have used it to change keys but when you resolved back to the original progression, you released the tension.

Yeah.... I'd say go with it like it is.
