Ok so I tried this on a textured wall with egg shell paint and no surprise it did not work! I was able to savage most of it and cut the ruined pieces out. After I clean up the mess I made I went and bought some smooth boards at hardware to store to a fix the mural to.  Overall, it turned out great! Everyone loves the aspen trees in my bedroom and comments on how good it looks. For the price I paid I cannot complain. Thanks Wayfair!
