Very adorable! Great job! I bet she'll be really happy with it. 
Nice use of blues and reds and the Anti-Aliasing and mixing between them. The way you did the lips is nice with the blue surrounding to soften them up. The only thing I can think to help would be to keep going back to the form vs the light source. I think you're doing a great job with it, but I bet you could add a little more depth in the details. Keep up this awesome work! 
Will take note! OuO hehe and thank you so much! <:D
