I think your model is great, and as everyone else states, a good texture will finish it off... However, it doesn't (imho) need anything added. The way you rendered th picture makes it look as if you have only one side part, and I honestly think that is what makes it looks "wierd". Other than that, I think the model looks pretty good for a bryce creation, and also, it looks good for a "slow moving, destorier" If it is a fighter however, use, some sweeped down wings might work better.
