Hi there, and welcome to dA. I just looked at your portrait of Lana Del Rey it's gorgeous! You deserve much more attention. With your talent I'm sure it will be no problem, so just go out there and promote yourself, haha
Use the forum, as you might already do. I found you there, but personally I'm way too lazy to use it. So join groups, be nice and all that. And remember, what you give is what you get d: There's so many things you can do
