Great job!
You know, it can be helpful to redo projects occasionally. In doing it again, you usually do it faster. I’ve even heard of an exercise where for say a week, each day you set a timer and do the same sculpt in the same length of time. Each time, you will get further in the sculpt and it will get better and better. I bet if you were to do Melvin again, it wouldn’t take you a day!
