Looks fine to me as is.
Only possible thing might be to continue the vertical lines down from the top with the additional three little circles (are those little one inch mini-bevels?). That may make it a little too Deco, tho... and sort of spoils the over-all curvilinear motif.
Sometimes it's best just to stop and not over think a design....;-))))
If you have the time, patience, and where-with-all try it just as you have it now, then cut whatever variations strike your fancy and just try them out in that spot you are not sure of. Look at each one and ponder it a bit. This is something I have done in the past myself. It is, after all, YOUR artwork and you should be comfortable with it.
