Hello, and welcome to deviantArt! I hope your time here is a pleasant one and that you will get the chance to see all of what d.A has to offer!
Here are some things to help get you started.
groups.deviantart.com/<--- Groups of interest you can look into and eventually share artwork within the community! This wonderful option helps get you recognized, receive watchers, comments and maybe several 'favorites' of your work.
help.deviantart.com/<--- The help desk- should you have any problems or questions. There is a search engine bar at the top, should you need to locate a certain situation and/or problem.
"Share a llama, get a llama!"
<--- The d.A Llama. He's adorable and fun to share! He hasn't any real purpose, other than to encourage deviantArtists to visit other, fellow d.A members pages and art work. The more you collect, the better your llama collection will be! Save the right amount and your llama's appearance will surely change. Use extra points to "dress" him/her up with bow ties, sunglasses and the like!
Helpful tip: Remember, communication is key. Start commenting, favorite other deviants' artwork, and maybe add possible watches to your watcher's list. Get involved, let yourself be known. This also helps getting yourself and your wonderful artwork out in the open, as these actions sometimes bring in many deviants to seek out your page.
