Hello, fellow artist and writer -- welcome! A couple of places you can check out for art and writing that I get a lot of inspiration in (and good rewards):

Freewriters Community -- Daily writing prompts and a world of other fun stuff -- very supportive!

Ink Well Community -- Another excellent writing community, more free form with good prompts and good contests in there too from time to time.

Sketchbook Community and Art Community -- all great art communities! The latter is new and is present offering a contest for artists to be featured on its banner -- definitely check that out!

DIYHub Community -- When you want to show your art and the process, this is a good spot just like Sketchbook is.

Alien Art Hive Community -- generally WEIRDSVILLE art, lots of aliens and science fiction themed art, but very supportive -- it is where I started my art journey on Hive as a fractal artist!

GEMS Community -- generally working to retain good content producers by rewarding them WELL. Put your BEST work in here every so often -- not too much, but drop a gem in here from time to time!

Enjoy and again, welcome -- and from what I see of your drawings, you're an amazing artist and bound to do well here with consistent work!
