How to paint - Khorne Hero on horse

I have a descend 1500 point Warriors of Chaos list but only one hero on foot additionally caring a Khorne icon. I like the models for Hero/Lord on horse and Juggernaut that GW has in offer but I decided that I have so many bits that I will do my own small conversions. I started my work with the hero on horse.
