It's pretty faithful to the original, but the percussions are more present here which boost the "class" of the music.
By the way, where did you find the sheet? It seems to be nowhere on the Internet...
For what it is - a nostalgic little loop - the song is quite good! I do think it could have been a little louder, seeing as the Hall Of Fame music was always a triumphant little piece and this, while having the right instrumental usage, is a bit quiet for that. There's a tiny cymbal glitch when it loops, but for the most part this is a solid little nostalgic blip. =D Good job!
I can't believe nobody else has commented on this!
I would just like to say that as a pokemon player since i was 5, that this was a truly amazing song. Really brings back the memories. Keep up the good work as you have great potential!
P.S. you did a really good job on the remake 0.0
Please contact me if you would like to use this in a project. We can discuss the details.
