I have a son who had a 16" tall mohawk. He spent most of his time coloring and gluing. He gave up, but managed to get some great pics before it was all over.
Green spikes? I have nothin' against 'em. I think you could spike and just use gel and your natural color and still look cool. However, Knight, I'd be reluctant to mess with all the good things you've got going (cute little shit....lol) unless you NEED to make a statement.
For me, making a statement is dressing in boarder shorts, and acting 25 instead of 50, which I'll be this year. People think I'm the oldest big brother of my boys. (Yawn) It's getting to be too much work to look this young. But it's fun, and the boys shop for me sometimes.
But you have more "inner-G" than me.
My advice--please yourself first. Those who love you most will help you enjoy what you love most. Please the misses as a pleasant surprise, not as a regular routine that sometimes can appear as a demand (in some personality types).
You'll still look cute no matter what you do.
