That looks good. There's a more ambitious one here if you want to try it. This is the one I cut, aluminium naturally:

When the machine isn't sufficiently rigid it's better to lower the depth of cut and keep the feedrate at the correct value. The reason for this is clearly you need to lower the force on the cutter, which lowering the depth of cut will of course do, but you don't want to lower the feedrate as that lowers the chipload (assuming constant spindle speed), as that will cause more wear on the cutter and more heat.
