Hello Md R. This is clearly a act of plagiarism, in most places in the world this sort of unethical activity is not tolerated. If all you do is photoshop other people's original work and claim it as yours, please apply for a photo editing contest or job since that is clearly your strong suit. This a very unhealthy habit that will not get you far in life. So for your own sake please do not copy other peoples work. Also, don't try to fool your employers it will only backfire on you.
