lol My cat just deleted my whole comment before I could send it.
This is soooo beautiful!! The water and the snow looks amazing. And the depth you created with the changing colours of the snow and plants is great. The mountain looks totally real and the colours of the Northern Lights are beautiful. I'm impressed how smooth you blended it, the few times I tried oil I couldn't even blend it a fraction amount of what you did here.
Thanks for your comment. I think I used a layer of a clear blending gel that I put on after painting the background with black acrylic. I'm not sure what it's called. You can also thin out the paint a bit with mineral spirits or something to make it blend better. BTW your work is beautiful.
