DeviantART has never really been a good place for true pixel art. Now that the last hope, our dedicated gallery director is gone for unknown time, I give up too.
If you want to keep up with the rest of the pixel world, I suggest going to the PixelJoint community
am quite active there too.
Its a website where you can create your own gallery, just as deviantART but for pixel art only.
Every week there is a new challenge, there is an active forum and lots of people out there willing to help you.
I will continue running collaborations from out there too.
If pixeljoint only is not enough for you, you might also want to join Pixelation
Its a pixel art forum, where lots of experienced pixel artists come, share their art and have collaborations and challenges too.
See you there soon!
