These Spikes are surprisingly versatile, and you can quickly give them a 3D edge or gradient overlay to add a bit more interest.
Open a new image in PS, and right click the Lasso Tool () and select Polygonal Lasso Tool, then draw spikes on your image. Make sure you make a complete shape so when you’ve finished it becomes selected like this:

Go to Layer > Flatten Image, then go to File > Save! Here’s mine:
