Hey Ondrej! I did indeed read everything, and it was really touching. Hopefully we can help you improve in this forum!
Most people are told the same about art, which is kind of sad. Sometimes its cultural, other times its just pure ignorance. "It is not useful", "You'll starve". I guess people never stop to pay attention to their surrounding. Our cities are literally built by human hands, every house and building we step into was designed and structured by clever people. Yet they don't view that as art. Every furniture around them, chairs and couches were designed with human anatomy in mind, yet they don't view them as artists. Every song that people listen to, was crafted by an enthusiastic musician, and only then, do people start considering them as artists.
I guess they indeed never stop to think about the aesthetics around us, that were imagined and crafted by ARTISTS.
I'm glad to see that this never killed your enthusiasm and love for drawing though. Surviving this stage has always been the toughest, and it is where the most potential artists are lost. It is where most of us stop drawing. Anyway, rant aside, I'm looking forward to seeing more of your blog and see you develop! This forum is quite active for an art forum, so don't be shy to ask our fellow members for help!
