I don't think you should need to label your work to make it apparent what it is. Either leave it up to interpretation to the viewer, or have the work tell itself.
And his post was constructive. I don't think it's that he can't 'appreciate' the depth of your piece, but that it's so mind-numbingly flashy that it's nearly impossible to make out without ripping out one frame. If you're trying to give an underlying message that it hurts to look at, then do so with the art itself, not by bright eye-sore colours flashing rapidly at a seizure inducing level.
