Even if you feel absolutely nothing. Which in itself is quite an achievement. If a deviation can leave you totally numb, then it must be really special.
How do you like my photography or artwork?
Do you think it's super boring or just too average to comment on? You can tell me that! I won't get insulted.
Does it make you think about something? Or maybe you want to ask questions?
The current problem with dA today is:
Too many submissions, too few spectators. People have no time to leave comments since they're busy watching... watching someone else than you!
People are cowards. They don't dare to leave negative (but constructive) criticism. Most times they just write "Good!", "Nice!". I suppose it's more than enough in most cases, but usually not very helpful at all.
