If you're ever going to use it, sure... If you're just making it for the experience, may as well make something you're going to use in-game or as a showcase of your skills. If you don't have a use for it, you could make it higher-poly and make it a showcase item.
yeah. I seem to have a problem with models tbh. I dunno wether to put them in-game or just do them for showcase. But I usually do models for games, this time round I'll make it a showcase item.
