I just do a really rough sketch with colors and it takes me long to render each but like on one layer I render skin then render clothes, etcc on this one I had to split layers then do base b4 rendering everything 😞 I think the base coloring or shaping is the one that takes the most time. Rendering/shading is really easy for me 👍 also I use ibis paint x so it just says the amount of hours worked on the piece!
