Boy a lot sure has happened while I've been gone.
Well, you seem to be getting along just fine, all the artwork you've posted is absolutely stunning--but I figured I'd throw my two cents in anyway.
Everyone else has been focusing on the inspiration and the painting itself, which is good because I get stuck there all the time and probably wouldn't be able to offer advice on that... but I can say a few things about making the area a place you want to work.
Anywhere I have to spend a lot of time, I like to buy one of those $20 electric water kettles from Target or wherever, and keep a stash of my thrift store mugs so I can always cozy up with a mug of tea. It's the best thing, especially if it's cold out (or cold inside!), and it'll warm you up all the way through and I can't say enough good things about it. Plus just knowing that my kettle is there and I could make tea if I wanted makes it feel more like home, and when I run the kettle it makes that little steaming noise and then the click at the end and having a little noise like that makes me feel less alone.
You might also want to do a physical and spiritual sweeping--if you've made or bought a besom you could use that, but for something like this I should think any broom would work, especially if you want to actually sweep. I find a place always looks AND feels better after a good sweeping or vaccuuming, especially if I sing while I work. You might also want to smudge if you're not sensitive to burning herbs--smudge sticks can be a really good deal and they last a good long time and they do (in my experience) make a place feel better (and smell nice!).
I'm glad turning to Gaia seems to have really worked out well for you. I know I haven't said much beyond real standard space-cleansing advice, but I hope it helps you (or anyone) in some small way. I'd love to see more of your work!
Blessed be.
