Those people who post really good first carvings are few and far in between. Some people notice things more, some people just have an eye for making what they want line up with reality. I started carving bone, etc. before I started leatherworking, and I was pretty bad. Then I got a bit better after I started leatherworking because I started to see what would work best. It's not obvious, and tooling takes a lot of decision making. My husband, who is a designer and very good at making great looking drawings, doesn't instinctively know how to tool. In fact, when I asked for advice when I first started, I ended up liking my own decisions better than his advice. I'm still only so-so at tooling, but I think half of getting where you need to be is discovering the style that you're best at. You may not be best at Sheridan. Or maybe you need to try Sheridan. Or you may be trying to tool patterns that are too small. Who knows.
