Welcome to dA, where you can practically accomplish any wishes you want for becoming a well-renowned artist.
Do you have many questions about this site? Then here's the
Help & F.A.Q. page for that. If one of your questions still isn't answered, you're free to click on my avatar (face) and leave me either a note or a comment.
Here are a few places to help get you settled in.
You can introduce yourself at the
Welcome Center Forum, if you'd like.
You can share your art at the
Deviation ThumbShare Forum.
And finally, there's
Groups you can join that allows you to meet other people in it and share art there as well.
Hopefully that was enough to help you out.
