There's no need for arguing. I'm not very good at taking critique either, so I feel you, and the only reason I said anything was because you specifically wrote "what do you think guys & gals" in the description, and I thought that the lighting looked wrong. After looking at the painting for a while, I think I've figured out what looked 'wrong', and it's the lack of value changes in areas that are in shadow. Her body looks flat, you know? And where's the cast shadow from the hood?
, I made a quick paintover to show what I'm talking about. I may have went a little overboard with the cast shadow (and the hood shouldn't actually be that bright), but the main focus here was on the suit. Looks better with some distinction of form, doesn't it? Although I still feel like the lightest areas shouldn't be where they are, but lighting is definitely not my strongest suit so I'm not going to argue with that. Have you seen Sycra
's series on Foundations of Light and Shadow? It taught me a lot about the basics of lighting, even though I still have a lot to learn. As do you.
I hope you learn something from this and don't take it as an insult. I'm only trying to help, but if you really feel that a 17-year-old without art education doesn't know shit, then that's your opinion. Good luck.
