Well, I'm a new deviant here, and honestly, seeing that there are people who actually like my stuff means more to me than anything. It's hard for me to get around though; I don't even have a tablet especially for drawing yet, and it's REALLY hard for art to get noticed when it's not digital ;~;
I like meaningful comments, because it allows me to make new friend, or have a fun conversation, and it makes me feel important. Compare to Watches and Favorites, these upsets me. Because I want to listen to their opinion, and its boring..... Especially when you do your best and nobody ever leaves a comment.
Being told that your art is terrible is generally the most impactful; even if you are good, the human mind likes to focus on the negatives, and ultimately the twenty people that disliked something get more attention than the 2,000 that liked it.
