Welcome to DA~! I hope you have a wonderful time here and meet many wonderful artists! You gallery is already looking amazing *o* Once you get settled in more, try joining some groups to get your artwork out there, or just to make friends with people who have similar interests!
No matter what, just be kind and courteous and if someone isn't, then just ignore them. The community has had an outbreak of trolls recently, so it's best to just ignore them. But I haven't run into any and chances are, you won't either ^^
so welcome have a great time!!
