You did a good job that it's the first attempt. I like the colors ^ ^ but now I'm gonna point out something that needs improvements, for example, the faces, the eyes, the neck and the shoulder. Here's the specific details: The face should be symmetrical. The left eye is bigger than the right eye. They should be the same size. the neck is kind of short and it should be longer. and the shoulder should be wider. Also you should keep the hair simple. There're too many lines. It's the first time I write a critique and I hope it's helpful to you
Pros: I really love the face shape, and how you did the layering of hair. This is also your first try at anime? Its really good, the general anatomy of the face and neck/body is really good, the lines are also very well done, and those cute little bows adds a little bit more to this picture c:
To Improve: The eyes are a teensy bit too low, which causes the forehead areo to look a little bit abnormal (and big) so just move the eyes up and your set! the mouth should also move a little bit downwards aswell, so it's closer to the chin Also what i suggest (if you have not done so) create a T on the face so you know where exactly to put all the facial features. The shading of the hair could also use a bit of more shading, and more blurring. (It looks a bit rushed) The shine shouldn't be put on random or every streak of the hair, rather just put it near the forehead.
Overall this is a very great piece and I cant wait to see in the future how much you improve!
Im really sorry if I sounded harsh or mean, this is the internet, you can't read other people's face expressions XD
