Portrait sketch

trying to make a Portrait sketch of my Friend Copper. Just a few things wrong with it I already noticed. Besides the Eyes being Derped. The eyes are too big and the Nose is too small. Since I had no picture/ in person reference of her I had to guess.. Started putting her in a Dress like outfit similar to what Cirno wears but Never got to finishing so. I guess it's ok on how it came out.. :L I generally put more effort in Portraits.. Just hope you like it! XD Bugs me on how it came out though.. :L I Had Not one reference of her when I was sketching this out.. It could be alot better.. Maybe I should try with Pen next time.. At least for the hair..

Only parts of her head I've seen before was the top and the tip of her hair.. :L

The person I based this portrait on:
