Hello!
As you can see, you can submit your works in folders.
Right now there's 4 folders:
1-Traditional for pencil works
2-digital for digital work (and by that i mean drawings not logo's and website things)
3-Photography (you can submit photo manipulations as well in that folder)
4- and finally the coloring folder ( like a lot of people coloring manga digitally or making line arts )
Have fun
