Ooh~!<3
That is great~<333
Piratekingtai was right, the way the paper colour is and the colour of the lines really go well together and suit Ren very nicely~<33
The eye shape is great; it's perfect for Ren's face~! >w<
The flower is amazing, I really like it~
I'm no good at drawing flowers...
I love the shape of the shoulders, the go really wel with her face, and the angle is really great~<3

Her face is a bit long, it's true, but I think that's it's because you made it kind of thin. She needs... uhm... Cheek fat. xD;
Her hair is really nice, you got the shape and style pretty much perfet~<3
It could use a little more, uhm.... tapering. :3
You should try tapering~
I actually find it fun... Oo;
xD;
Her expression is really cute~
The eyes, you really pulled off perfectly~<3
She's missing a tiny bit of hair; in back, she has a little bit that hangs down... OuO;
And The piggytail things don't totally touch her head in this, but that's all right- artistic interperatation, right~? x3

Thanks a ton~<333
I really really appreciate this~<3
I'm super happy you posted it~<333
Thankyouthankyouthankyou~<3
You're great at drawing, you got nothing to worry about, if you think people want to make fun of your stuff. Nothing to worry about at ALL. :3
You have a lot of talent; you just need to focus and fine tune it~<3

The color of the lineart suits this piece perfectly. I love the way it looks, and you have a cute style~

My only concern is the head: it seems a bit long. The hair comes up so much that it feels off of proportion. I would recommend sketching a size you find suitable and work from that.

I know I have a problem with head sizes myself, so I hope you don't think I'm trying to focus on any negativity.

But if this is how you wanted it to look, good job! keep up the good work, I'll keep watching~
