2D and 3D animation struggle

im following the course to build a portfolio and i believe i followed everything right for the most part… im 22 minutes into 2d & 3d animation but i cant seem to get the pictures to glow with the saturation behind the other pictures… im not sure if my main page is covering the photo or what is wrong

any help is greatly appreciated.
