Man, you really know your stuff about lightsources... I like the hazy fog that blends into the picture, and I'm very fond of the dreamy background. I really wouldn't say your filtering is bad, nor would I say the entirety is bad. The shading is decent; the only thing I'd say is that the pose is a little weird.
Well thank you, though I pretty much disagree with everything you have said lolol I find the light source very ambiguous, and it doesn't really match the sky and it's overall sloppy looking. I've only uploaded this because I spent like 3 hours on it, which I should really stop doing because I'm never happy with the way they come out. As for the pose I actually adore the it, as I've kept the original sketch because I didn't want to lose it.
