Art's a difficult thing to stick with. Ultimately, there will always be a group of people who will look at what you create and go, "This is fucking shit I hate it." So you are RIGHT, everyone is a critic about everything. We all have our likes and dislikes and because of this we all feel our viewpoint is important for others to acknowledge. This is especially hard to hear as an artist because you work your heart out on a project and it doesn't get the recognition you feel it deserves. The important thing to remember though is that someone out there will like your "shitty dick drawings" and see some sort of beauty in it, and that's why artists keep painting, writers keep writing, and musicians keep playing.
4/5 Keep playing, bitch!
