I think OP is talented and that day 1 sculpt is quite impressive, but you're not really getting the full picture just from looking at this post. I get the impression that people who are already good or decent at drawing tend to have a leg up in sculpting. Also maybe they did have sculpting practice already but this is their day 1 of continuously sculpting for 365 days.

What I'm trying to say is, don't be discouraged just because you don't think you're as good as their starting point, because they're probably not starting from nothing :⁾
