Why not a transparent image is superimposed on the image?

When I tried to put a transparent photo on another photo, it did not overlap transparent, here's a photo after applying:

here is the code:
img = Image.open('screen.png') #screenshot
img2 = Image.open('Without name-1.png') #transparent photo
img.paste(img2, (0, 0)) #overlay
img.save('new.png') #save

what could be wrong?
thank you

With PIL is not working.
But you can solve this problem using openCV. By multiplying the respective areas of the image on the coefficients. For example:
img = 0.7 * img 
img1 = 0.3 * img1
img2 = img + img1
