I am a noob. Whenever I start a new hobby, I always ask how I can get better faster. You never get a truly satisfying answer to this question because people can only tell you what they think works for them. There are never any objective measurements proving the advantages of one method over another. That is why I upload all of my work, so in the future, other people will be able to compare my progress with others and objectively state, "don't do it this way."
This is all of the drawings I've made in the past 15 years except for a couple I made years ago (that I can't find) and stuff I spent less than 10 minutes on.
