The cracks give it character. Like wrinkles in old model railroaders.
Once you paint and apply turf and ground foam, you'll never see the cracks. You might try mixing with a bit more water next time, to see if that makes a difference. But it doesn't really matter. Mine cracks all the time, and I'm always happy with the end result.
It takes an iron man to play with a toy iron horse.

This is almost certainly a case of the gypsolite drying too quickly. Most probably because the underlying plaster absorbed the water from it. I use structolite (a very similar product) in various thicknesses and have never had a crack. Always moisten any adjacent hydrophilic material before applying the plaster or plaster mix like these brown coats. That holds true for bricks and mortar too. you should NOT need glue but what the heck, if you have extra use it up. It shouldn't hurt either.
