Hi, I have a good eye, but a lazy hand, so you can ignore my cirtisizms, but they are constructive...
1. The splash the tornado wind is making should be circular if its a tornado. You could have made it a meteor coming from the opposite slant of the tornado.
2. The doorway looks a bit off, it doesn't seem parallel with the rest of the building.
3. The clouds seem a bit... odd. I would have left them out, considering how awesome everything else looks. (But I have to point out I am pretty lazy, and would stop whenever it seems "ok" :P)
4. Keep up the good work! Your drawing skills are awesome, you just need to work a bit on what exactly your drawing :P. Great job (shading, perspective, waves, cliff. awesome).
[edit:] about the clouds, its only the foremost layer that the tornado is "coming from" that are odd. The background layer of sky is awesomly shaded and provides the perfect touch to a pretty awesome drawing.
