The popular way to draw axolotls looks NOTHING like how axolotls actually look. I draw him with a big 'ol bobble head and stuff, but they don't really look anything like that haha. But, to use that style, it's pretty easy.
for traditional art, it really depends on what medium you prefer. In my sketchbook, I sketch my drawing, outline it with micron pens, erase the sketch, and then I use alcohol markers to color.
you just have to remember that you can't do any adjustments once you finish the lineart, so you have to be very careful. In digital art, you can resize and adjust and erase to your hearts content, but if you are using ink and paper, make sure your sketch is exactly what you want before doing anything permanent.
