What drew me here first were her adorable eyes but I must say this is extremely appealing, the mane is absolutely gorgeous and fun to look at; especially the eyes.
I just noticed the left side of her head there is a line not meeting a certain area near her lower eyelash. I would also try to avoid having the eyes so close to her ears, but thats just me.
Now on a side note, i would have also put emphasis on the tip of her mane where theres usually a hook like effect on front of her face. This next one is just a suggestion, i would have coloured it, and put in a lot of work on colouring the eyes so they really pop out with a little background colour to it as well so that it makes it more effective. I also would have included gummy buried in her mane for the fun of it but overall great job on this!
