Sorry, but if your goal is to become a pro at this, you NEED to put in the time. 30-40 minutes every day simply isn't going to cut it. Many people on here will tell you that "as long as your just draw something every day, you're good", which is just a cope. The truth is, if you want to see the kind of improvement you're looking for, you have to put in the work. And why is it so hard to draw for 8 hours a day, anyway? People have all kinds of shitty jobs that they do for 8 hours a day, from fast food work, to doing oil and tire changes all day. All you have to do is sit in your room and draw while eating snacks and shit. WHOAAAA SO HARD.....
