I've been on Behance for years but I just used to upload stuff and that it as an easy, secondary portfolio.
I've found recently that there's a bit of a formula if you want to get noticed though. (Not that I'm actually following it).
People like to read a bit of a story of the project as essentially they want to learn about what caught their eye and also development work like sketches.
They say around 20 images is ideal.
Those long images work well for info graphics and games like the example.
I did something like that myself for t-shirt designs.

Other main thing is to put up an appealing cover image which sounds obvious.
I've recently found by accident, the way to get appreciations, views and followers is to appreciate, follow and comment on other users in a selective way.
If someone who has a lot of followers returns the favour then your exposure goes WAY up.
On Behance I get a dribble of views and followers but a while back I followed someone who's work I liked and they followed me back.
Turned out they had a lot of followers and the next day I had something like 90 appreciations and followers.
I'm not very good at playing the social media game but this one was pretty obvious.
