I've done some art feedback in the past for people in the forums such as the one below and I'd like to do more critiques in this style:
Basically, I will try to give fairly objective feedback, and then I try to show you what I mean by editing your presented artwork to match my advice. I can help if it's regarding background, composition, colours, shading, animal anatomy, and most of all, human anatomy. In a way, it's performing plastic surgery on your artwork.
There's actual "plastic surgery" videos on art if you want to see how it works in real time~ (thanks Ran for finding the video!)
My own artwork is around this level if you're wondering if it's worth your time to get feedback from an internet stranger. I'm just your typical anime artist.
I can analyse and edit about 3-5 artworks within the limits of my ability before I close ithe thread!
Please let me try and critique / perform plastic surgery on your artwork!
