Welcome to DA, a place for art of all kinds! Art here ranges from literature works, to traditional and digital drawings, and even photography. You seem quite new, having joined just this week! Depending on how long your stay here on Deviantart is, your work will improve, especially if you accept constructive criticism.
I hope you enjoy it here. Oh, and do ignore the people who say they hate your art, they're just jealous of your talent~
