some advice:

the rocks arent cut out properly. you could see white around its edges. you should also have more variety between the rocks from the looks of it.. it looks like you just kept flipping them horizontally. the glaring light in the middle is distracting and its not how the lighting should be. also if the rocks are floating there should be a shadow reflecting on the ground. finally take out the text photo manips dont need your name in the middle of it
