Attempted to make poro rider sejuani

I'm trying to get poro rider sejuani at my collection of LoL champions (found here: http://www.thingiverse.com/thing:668894)

Because I like her and someone asked me if I could upload her to.

I got a little creative and mixed som sejuani skin and did some changes. This is the result. Let me know what you think and please help me to improve her to get the best result
