Some quick feedback for the contest:
I would like to see a change so that the contest entries are on an endless scroller instead of pages. As soon as it got to 3-4 pages I at least were more likely to skip something.
Like on artstation, it would be nice to be able to pick a- or crop your image so that the thumbnail is actually somewhat appealing. Right now it’s just centered I believe.
There are also a lot of questions at the start of every contest. Some at least are tied to the theme and thus can’t be answered in the general FAQ that you made ahead of time. So I would encourage you to be more active in the forums around these times. Even if it’s only once a week that you take an hour or two to answer stuff. It does a lot.
And lastly. A very personal opinion, so I would love to hear what others think as well. Please don’t always have repeating themes. Fall is always halloween, winter is always candy, spring (which, I imagine, is really what this one would have been) is the gangs. I would love to see different themes, different challenges. What about creatures, architecture, landscapes, vehicles or even sequential art like comics or storyboards. If it’s always the same it becomes a somewhat skewed of the concept art industry. You’re gonna have to do a lot more than drawing final renders of characters in a single angle.
Just food for thought.
