Wow, thanks a lot for the advice Hamachi. I asked Rio to have my account deleted so I won't be around anymore, but I'll definitely follow your advice.
I really appreciate your taking the time to give me such valuable advice. I'll try to buy some of the books you suggested.
I'm going to the supermarket to buy some pencils this afternoon, but only if they're really cheap. If I have some money left, I'll buy some blank A4 paper, I promise.
Right now, I'm not really focusing on manga anyway. I mostly draw little doodles and I try to do some exercises every day such as drawing shapes.
I don't mind doing things over and over again.
I'll practice every day—I always assume that what I've done could be better, because it's the truth.
I'm not a professional.
