Spruce_Branchy_lines.png

What do you think of this snowfilly's design?
Filly's name is Yelovaya Lapka (which translates as "Little Spruce Branch") because of her spiky mane and tail, her cutiemark is just a dark-green three-ended spruce branch.
Despite of her "thorny" appearance, she's a very soft (by heart and, of course, fur) and kind filly who likes to explore surrounding nature by herself when her parents are at work.
I will try to color her later in Photoshop or just Paint.net, but firstly I want to ask you all: is there something I should change in design and/or lines?
