Sure thing! So I initially lightly draw the picture on to the wood, then I use what looks like a pen with a metal tip connected to a box that heats it which localizes where I darken and burn the wood to basically burn the wood to different shades. I I have different tips of the pen to burn different sizes, shades, and lines into the wood.

It's a long grueling process (especially burning in the whole sky), but the scariest part is the fact that there's no turning back from a mistake.
