I hate to say it, but if it's feeling like blues, you ain't playing it right.
Sure, there's some cross over and pentatonics for sure. But way more notes in between, open strings, hammer ons hammer offs or pull offs, double stops, double stop bends etc.
At least for chickin pickin - get the Brent Mason Hotlick vid, that's where I started.
If you learn all the open scales, Jerry reed, Don Rich and the guy from Haggards band's licks - those guys are just what all of us modern players have ripped off and elaborated on. Theres more swing and jazzy stuff to it as well. Triplets and stuff is when it gets fun.
And you have to get fast to do that stuff and be able to claw and thumb pick ideally.
But alot of guys do it hybrid style too. I could never get enough power with my other fingers whilst pinching a flat pick between my thumb and index, which is why I like the thumb so much. I need my index finger as it's the strongest one for me and my middle finger is the fastest. But when you start clawing is when it really comes in handy not pinching a pick.
