Angraecums are not the easiest of plants to grow, and I would not consider them as beginners orchids. But having said that let me add that your choice of media is fine. However, it is potted too high up. It should be down to where the roots meet the vertical growth.
While you can display an orchid inside of a decorative pot, it is not advisable to grow it inside of one. Why? It can lead to watering and drying issues.
A common mistake is to grow them in too much sun. It would enjoy morning sun, East window, of perhaps 3 hours of sun, otherwise bright. Never let them stay dry for too long between waterings. Fertilize weakly every other month. They like temperatures between 60-85, but will tolerate high and low extremes on occasion for a few hours.
