I know from experience one of the hardest style screwtip horn to make is an internal style screwtip. At least for me. One has to be absolutely sure that is everything (horn, collar and tip) is executed properly or everything won't be in line with the horn. I'd have to say Tim from you pics it looks like you did just fine,,,,,,as usual. Is it represented of a Berks style?
Coloration, as you know, is subject to personal tastes. Some like it , some don't, some are in the middle. For me it depends on the horn. If there isn't much white I like to color it for me, but a customer may think different. Overall, I like it just fine. Great job again Tim. I'm sure the crowds in Lexington will like them.
