I have recently beed doing quite a few manips and was wondering the price and what I could do to improve them. I'm mainly looking for what I can do to improve.

Your art is looking great so far! I especially love the top one.

I would say watch some tutorials (there are some good ones on HEE, I'll edit them in in a sec), and practice as much as you can!

Also, I think many artists would be willing to give you a few tips.

Edit: Eh, just have the whole forum:

it was really helpful to me, and I hope it works for you, too!

Looking good so far! I would say around 15-20k.

Just a few things to brush up on, you have an awesome start to your hair painting. One thing I would add is some defined shadow and highlights. It will make the hair really pop :) I'd also recommend playing around with grounding, lighting, and a little eye painting.
You're off to a really good start, keep going! :D
