Tales of Lentari

Hello fans of Lentari! As work progresses on the third and final installment of the Bakkian Chronicles, I started wondering about what should be depicted on the book cover. So I have a question for fans of fantasy:

What do you think are elements of a good fantasy cover? Something eye-catching, or colorful, or whimsical?

With regards to the other covers, the first book conveyed what I thought was a gorgeous scene of a forest through the open portal in the mansion. The second was a whimsical scene where Pryllan and Peanut meet face to face for the first time. Granted, without disclosing details on what will happen with Amulet of Aria, all I will say that the final confrontation with Celestia, the sister, will take place. And let’s just say that she really, really, and I do mean really wants Mikal. There will be battles, dragon riding on multiple dragons (gasp!), and accidental teleportations, just to name a few. Oh, did I mention that the battle finds its way to our world??

Suggestions? Let me know what you guys feel makes a good cover for a fantasy story!
