This is an interesting take on global warming haha
but for real the picture is very nice and also super cozy! Not only is the background very friendly looking, but your sun character just looks super kind and huggy too. The rainbow over the earth makes it look happy too lol. I also absolutely love the shading, it's very smooth and natural. The way you did the light from the sun on the Earth is very natural looking too. And the anatomy/posing is perfect! Awesome work, keep it coming!!

We need to make sure the sun's warm embrace on the earth doesn't get too hot.
