Your ring is stunning!!! Wow. Nothing wrong with the craftsmanship or anything like that.
But my first impression is that it overwhelms the center stone. Also, a cushion faces up a bit smaller than a princess cut. There will be a difference in how it looks in a setting and on the finger.
If you don't like the proportion of the stone to the setting then the only options are to either have it redone in smaller melee ( I have a feeling the inspiration ring has smaller melee) or have it done with fewer rows of micropave, or try it on in person and see how you like it on your finger. You may very well like it better in person as the setting is soooo bling bling!!!
The whole setting, including the shank would have to be scaled down in smaller melee if you want to change the proportions, not just the halo part can be redone.
