Need Advice on New Haircut Suggestions Appreciated

I'm on the Left I am in need of a new haircut and I am not really sure where to go with it. I used to only wear my hear shorter in a Caesar cut but lately I have been spiking it and I like how it looks usually. This is the most recent picture I have of me (guy on the left). Any suggestions would be extremely helpful as I am just not sure where to go with this. If it is hard to tell from the picture I have pretty thick darker brown hair. My hair has a slight natural curl and it usually responds well to product.
