Yes, it's the first occasion, but I'm asking for help, Not for myself, but for my sister (my internet sister)

and for my dear friend
Please, have a heart, and help me!!!
First, I'm starting with my sister:
My little sister doesn't have a very good life, plus she suffers from mental illnesses like discalculation (she has serious problems with Maths, and etc.), and she has a problem with understanding what people talk about (however she does her best to try understand everyone). She is not good at foreign languages as well, but she tries hard. Her life isn't happy, and I'm sad because I can't protect her from the abuse and hurt she gets. She is not my real sister, but I do everything to help her and make her smile and happy.
So, my sister's only chance to go to an art college (however she has two years until she reaches college), because that's her best skill. But she finds her drawings lifeless and dull, and she asks for advices how she would be able to improve her drawing skills. And she is not very wealthy, so she would do money commissions (cheap digital ones) for you as well. (I'll help her to make a payplay account or something like that if you guys are interested to commission from her)
What you should do:

Go and take a look at her gallery, first

Think it over, what and how she should improve her drawings to make them not to look lifeless

Then told it to me directly, or her (if you choose it, please don't use very complicated words because of her problems)

Please, make a very well detailed critique, because her life depends from it

Tutorials (she prefers the ones with lot of pictures, because of her problems) will be appreciated too

If you think her artwork worth a commission (only for 1-2$) then let us know it
Please, it's free to do these things, but for my sister it means her future!
And then my dear friend,
She was my first real dA friend and she turned out one of my best friends, not just here, but compare to some friends as well. She really needs money, that's why she opened her commissions some time ago. And definitely, she is one of the most generous people I have ever met. She tries to help me a lot, and that's why I'm trying to help her as well. Also, she is a very very good artist, her artworks are just amazing. If definitely worth to commission from her, even if it's a traditional or a digital drawing. But that's not all, she can make sculptures and little crafts as well. She tries everything to get money, and she would really appreciate your help.
What you should do:

Go and take a look at her gallery

If you like her artwork, commission from her (she has a payplay account)
Please, it would mean a lot to her!
Thank you very much for your attention

And I'm looking forward to see your comments here. ^^
