Wow, that looks really good! Although there is one thing I noticed that could be improved upon: I think it comes to to much of a point. In movies such as The Wizard of Oz, with the tornado in the first few scenes, the tornado has a large base. Although some tornados are very tall and skinny, with small points, the overall shape of yours is not like that type. The base in your type is generally about half the width of the top of the tornado. Other than this small thing, I think it looks excellent! |
