My favorite part is the brass sounding synth melody.

If you use sidechain compression on the plucky distorted synth when the piano keys come back in the last third of the song I think the mix would sound better. The melody is nice the composition just sounds a bit muddy at times because of the overlapping frequencies. EQing the levels of each sound can help also and like I already said sidechain is a life saver.

I really enjoyed the key change that transition was done well.

Damn I love unique variations on already established fantasy creatures. This is fantastic!
