Dang Toyotaboy, that looks awesome! Put me down for a set...!
But, since you ask... it is actually kind of hard for me to tell what the orange stuff on the right of the image is: is that a debris field, or a contrasted afternoon light effect?
If you're going for realism, my experience storm chasing by proxy via my brother, and watching hundreds of videos, is that in general a debris cloud from a "cone" tornado is not as far out, especially at the distance implied by the scale of the wheat field in your image. At closer range, a cone might have a debris cloud seemingly attached to it. A monster Wedge-style obliterator can sometimes be hard to separate from the debris field at any range.
I'm not meaning to pick on semantics, because your image is awesome and really fits the pin well. I like the lightning strike and in fact, one of the DVD's my brother produced and sold has a very similar image (cone funnel with a bolt) on the cover. The precip wall looks awesome as well. Just thought I would share some observations, since you asked. Either way, you can count me in as a buyer.
What does the other side look like? Might be neat if it was another view, or a different storm... maybe something more "urban" to tie into the tollway ramps on that side...?
