Serious Question about inspiring female black country artist...?

My first and biggest suggestion is to NOT "ACT' anything. If she is a true country artist, it will show through but she should e true to who she is. You say she is not 'twangy' as if that is a bad thing; it isn't and country fans are NOT leery of black country artists at all! We don't care what your skin color or nationality is, what we do care about is the music. I personally love 'country blues' I'd suggest she educate herself as to where country music comes from historically, listen to the classic old school artists, many of whom crossed the bridge as you say and work her way up. You'll find that the artists that have longevity are the ones who sang about events that speak to everyone and stand the test of time, lyrically. Performing to a broad audience of all ages would e a step in the right direction. If she chooses to adapt to what Nashville puts out today, odds are she will be here to day and gone tomorrow because that's the world we live in....sales, sales, sales. Great for the business but not for the artist

One of the most important aspects of singing well involves correct breathing. Now you would think that we would already do this correctly. Try a site like https://tr.im/IX74b which has the best vocal exercises

After all if we couldn't breathe we wouldn't be alive! But in reality many people have bad breathing habits caused by a variety of things including poor posture and our often frantic lifestyles. Learning how to control your breathing is one of the keys to improving your voice.

Singing requires that you are able to take in enough air quickly before you are about to sing a line and then let this air out in a regular and controlled way whilst singing the notes. The mistake many novice singers do is to take a quick shallow gasp of air into the top of the lungs. This results in there being insufficient air, to get you through the line you are singing, and you will end up dropping notes. I'm sure you can relate to this experience and can remember times when you have had to quickly take in more air half way through the line or note you are singing.
