Colorful Southwest Canyon Painting authentic

I love all the beautiful canyons that are all over the Southwest region of America.
This is an example of one that has some pink and gold colors mainly and is very
light and bright. It also has above the rock formations some typical Southwest shrubs.
I have painted it with palette knives and oil paints , emphasizing the strong geometric
lines in the natural scenery. It has hardware on the back, making it ready
for wall mounting . And all 4 side edges are painted authentic with colors matching the front.
