High range belting... how do I strengthen this part of my voice...?

Hey guys I'm a newbie here.... I just began fronting my first real band and I wanna tackle it and be the best I can... our set list contains a lot of Chris Stapleton, HELLYEAH, Monster Truck... so strong, chesty sounding highs... here is a video of what I can do, and I need to find out how to work on this and make it better and stronger, wirh as much range as possible... this is me singing a piece of " Outlaw State Of Mind" by Chris Stapleton.... I don't know if I'm a baritone or tenor, so an opinion would be helpful... where do I go from here...?
