Composition seems alright. Aperture could be stopped down from the looks of it but I'm purely guessing since you have no exif data. If your lens is sharp wide-open (lots aren't), then focus stacking overcomes that DOF limitation, otherwise go wide then stop down a full stop and that normally reigns in shitty optics. Actually, the more I look, the more I can't tell if the corners of your lens are giving out horrid CA, or that's just the rock colours.
