I am sorry I didn't put the details on my post it skipped my mind, and yes I would love to share what I used, the brand of the colored pencils I am using is M&G Colored pencils by 36, and as for how I got the lemon color I used bright yellow for the high light , yellow ochre and orange for the middle tone, and brown and black for the dark tone, and I used an A4sketch pad for sketching and no I don't used Ai, I picked a picture online and manipulated it.
