I'd like more attention to be drawn to the magic effect in some way, to make it stand out from the model.

Dragon is magical by default.

Very nice, congrats on your entry and the effort put into it.

Next step would be, instead of drybrushing, try painting and highlighting these folds and scales on an individual basis. It is time consuming but it will push it to the next level.

I really like the color for the head and scales. As mentioned before, some brighter more flashy colors for the spell effects could look great.
