Both of the peices were definitely good. I applaud the way you create an atmosphere for each of the peices!
As someone said before, In the Opening Credits one, there is a clashing chord in the Clarinets. I think I know where you were going. If you had the chord piano and seperated, you could achieve a dark, mysterious sort of tone. It may not be for me to judge, but I would at least try it!
Also, the Battle in the Mist theme is good, but it doesn't take me anywhere. I think it would have a lot more potential if you added a "B" section to it, if you will.
Good job, and keep it up!
