The best way to get watched and commented on is to watch and comment on other artists. Roam the site. If you see stuff you like let them know, you'll almost always get a thank you or a peek into your gallery from them.
Check out the Clubs section, too ( http://clubs.sheezyart.com/ or click on the button under your avatar at the top of the page). Join one and get some interaction going.
Accounts on SheezyArt are never deleted; if you decide to leave you are free to delete all of your artwork and journals, hide your comments, stats, shoutbox, watches and friends, but your username will remain as well as your stats (though they will be hidden from view).
This is because deleting accounts would leave large holes everywhere. For example if you have a comment conversation with someone, deleting your account would result in a thread of someone appearing to be talking to themselves.
