Art supposed to be fun! But unfortunately, a lot of us, myself included, have a mind that is wired to see details and question every s-i-n-g-l-e thing, so much so that we are paralyzed by it. We can’t proceed until we have answers to our questions. In one sense, it is good to have such a mind, ones that questions everything and tries to get to the bottom of things; it is how we learn and discover new things. So for now, put away that critical mind that questions and challenges everything. And let’s have some fun with art. Don’t compare yourself to others. Everyone has a unique way and style of doing things. Some are better with figure drawing while others are more versed in landscapes. And here’s the thing: What you learn in one field can be carried on to the next, so nothing is wasted. Times spent learning to simplify things will help you later on when you get into logo design (for example). Furthermore, we all have strengths and weaknesses, and we all can improve!
Also, don’t worry about correct perspective because perspective in art is very recent. Egyptian and cave arts had no perspective. I love Van Gogh’s paintings but guess what? Perspective looks off! Don’t worry about line weight, “Should this line be bigger or smaller? And why?” You can use just one line weight throughout. And guess what? The famous Tintin comic used only one line weight, this style is called “ligne claire” or “Clear Line.” Google it and learn something new.
Correct perspective and line weight can always come later. For now, have fun. I’ll do some walkthrough later.
