Looks to me like it is starting to compost - just wait a bit longer.
It does look too dry though. Try keeping it moist. Also, if the sun is pounding on it, cover it up or shade it - compost does not really like the sun. If the outside of the pile is too dry, turn it a bit so the dry part goes to the center of the pile, and the middle parts comes out to the edges - that will also help get some oxygen into the pile.
But keep in mind - if you do nothing at all, it will still compost - but will just take a bit longer.
Also - if you find any earthworms in the pile, leave them there - they are a great sign, and do great work to the pile.
