The truth is that this was a work done only in grayscale, which I was able to complete in just over half a day, but generally speaking, yes, it took about a full day. And yes, the needles took the longest in this illustration, as I had to achieve a metallic effect, which I was able to do by playing with light grays in a staggered pattern... Glad you liked it, bro. Cheers 👋🏽
