Yes that framing is best.

If you want more of the mustard colours you would have to push curves up on the red channel hard if you are assigning each narrowband to a channel in Photoshop or use a higher combine ratio for the O111 and S11 if doing a colour combine otherwise Ha as green will dominate. A ratio of 4 or 6 for red might even be needed.

In a nut shell I think narrow band images should in fact generally be dominant in what ever colour you asign Ha to (in this case green) becasue Ha is far more abundant just like LRGB images of nebulae are Red dominant. Of course NB imaging is a dark art so anything goes and it comes down to your interpretation of aesthetics.
