Just a suggestion. . . I have that CD and that song does not have a funk feel to it. The snare is hitting on the 2 and the "ah" of 3. Try mimicking that original groove just to get out of the ordinary. It'll open your mind to more than just 2 & 4.
Also, from the way your licks sound, you play in church. Try doing some fills that are not "churchy."
Just suggestions. Expand your mind and you'll keep growing. You're doing a good job.
