Looks great. Might of come out a tad better with a darker shade % on that halftone black as you know. Instead of 10, maybe 15-20 with printing it as was. It was last right?
Another really good way to handle that is to print that read over top, knock out that halftone from the red by about 20% leaving it at 80% solid. You gotta allow for some black to come trough by printing that black halftone (far heavier than you have it now), under the red. Maybe a 30% halftone of black. ( I expect to use a little more of the darker color since it's going under. Boy, does that make a nice dark shade of red - not showing any halftones, (but it can get tricky). Too much can over power it and too little can obliterate it but can be outstanding if done right. I'm not suggestion you change anything at all. Looks great as it.
