Welcome to DeviantArt I hope you have a good time here. It's a great place to inspire and be inspired by all the wonderful people who share their work here. There's tons you can do here, and I hope you take the time out to explore as much of it as you can.
I see someone's given you a Core membership. Use it to the fullest It's not very different from a normal membership, and the extra features it does offer are a little meh (in my personal opinion), but it's good
Also, if you need anything, or you have any questions, feel free to ask me. I'll help as much as I can
Hope you have a good time. Looking forward to seeing more of you and your artworks around!!
