Hello, welcome to DeviantArt! I know that this can be quite a platform to tackle but there are some amazing groups that can help you with any questions you have ^-^.
As well as the general overview by Deviantart here:
help.deviantart.com/There's a lot of amazing groups where you can get a lot of support with your art that I highly recommend joining.
If you'd like to earn points, deviantart currency, here are some great links as well:
fav.me/d8du6j7 But there's plenty of other more specialized groups that you can join and submit to such as groups that share your interests. As you grow to become more comfortable with Deviantart, you'll learn to decorate your page, the usage of stamps, and about badges such as llamas and cake. It's always good to give back to the community so make sure to 'Watch' your favorite artists, 'Fav' work that you like, and comment on art to show your support.
And finally, a list of hidden gems on DA where you can find more help, art, ask accounts, and just the really fun, cool corners of Deviantart:
