Shading (?!)

Wow. So, it took a while, but I finally learned how to shade! Though, I obviously still have a lot to learn (like how to shade the dang face and make the back hair look decent), I think I did a pretty okay-ish job for a first time at shading.
As always, feedback is appreciated ^_^

Also, I'd like to give huge shoutouts to the shading tutorials I used to help me along the way. I modified them a bit so I could use them easier, but these are what helped me to shade.
Body and Skin by MayuriYandere. 
Hair by xXSarahliciousXx. (Idk about you but the pictures wouldn't show up for me so I improvised.)

Now, sadly, MayuriYandere seems to be pretty inactive, so questions about her tutorial probably won't be answered. :(
But, xXSarahliciousXx seems to be active occasionally, so if you have questions you might be able to ask. :D
