Hello there and welcome to DeviantART!
I'm eltoroguaco, though you can call me Guaco. I'm a regular artist and visitor of DA and has been chosen to welcome you to this site.
I see you already got submission covered, that's great!
You should go ahead and favourite some arts. You can browse others art any time by searching or going to the front page of this site
In addition, there's groups you can join. There's no limit to how many groups you can be a member of, so just search for stuff you love on the group search
groups.deviantart.com/ and click "Join group" on the ones you want to be a member of. Easy as that
Anyway, I'm here not only to advise, but to chat. If there anything you want to know about DeviantArt or me, just ask
