Dragon of Azure Skies: Nice and diverse track. The repetitiveness of the melody does not annoy and is quite catchy even (something I read was your goal). This is a great intro track!
The Tarragon Tarries On: Simple and catchy, fitting a pause song. Nice :)
Wyverns Abounding: A nice overworld theme. From this view, I expect the overworld to be very peaceful and calm, fit for exploring at your own times with your dragon pal. I like the occasional reverse cymbal. It sounds nice!
Dispute Among Drakes: This fits a simple battle very well. The repeating base is very nice, and the switch at 0:46 was very cool. This is definitely my favorite: it is just very well-executed, though quite simple!
Overall, I think you've got some very solid tracks here! They are all diverse, fitting different parts of the game, and they fit their themes very well. The sound quality is nice, the themes catchy (but not annoying after a while), and the dragon theme is present. Great job :D
