Here is how I made this pfp. First I searched up an image of an atom and I imported to procreate and made it be blue. then on another layer, I drew a N with a gradient from light blue to dark blue with outline shadows and I learned that technique from a shading scratch project. I then put the N letter over the atom and shaded the atom near the N to make it seem like the N is casting a shadow over the atom. It looks far more realistic if that's the look you're going for. It looks kinda trash honestly because I had to shrink it down so it could actually fit a pfp.
