It's fine. I don't think it's about how pretty the thing looks but the concept that you'd be showing. If something looks super ugly but there are some new/substantial ideas behind it people can look over that and still discuss the idea. Beyond a certain point if something is too early stage or there's nothing to show it's not very useful to do show HN.
