Hello! and welcome to DA!
Deviantart is an awesome place to share art, watch your favorite artists, feature your favorite artwork, and simply just interacting with others who have the same passion as you do! To get started, I would suggest checking out these links.
I know joining a new community as large as this can sometimes be overwhelming, so if you have any questions at all, feel free to contact me. I really love the work you have posted so far, and I hope to see more from you in the future.
