Bolo - Spellbound

• Add more layers - the result is a little simplistic because you've basically limited yourself to the same instruments that are in the original.
  
  
• Make it more dynamic - make an intro which builds up to something, then maybe introduce a break and build back up - that is, create a little story. This isn't really that easy to achieve on the SID but you are not limited in that same way.
  
  
• Add atmosphere - the mix is pretty dry, meaning there's very little reverb, delay, panning etc. It could also benefit from some spice here and there, sprinkled soundeffects, more percussion, what have you.
  
  

Kudos to you for tackling such a hard SID tune to remix on your first try! And you basically covered the tune in its entirety - respect!

I think your instrument choices are pretty good, but I wish you added more dynamics to them. They all sound pretty much the same throughout the entire remix, with not much variation from section to section, or even from note to note. Even if you're going for a more 'artificial' sound (not trying to mimic a human orchestra), if you add expression, articulation and/or ornamentation to those instruments from time to time, they will sound much more interesting to your listeners.

While I like the harpsichord (?) you introduced at 0:46), I would've switched to a different lead sound at 1:31 to keep things interesting.

That rising sound effect at 1:54 - very nice!

I really like the piccolo lead you introduced at 2:45, that's a nice touch!

Starting at 3:08 you are alternating between the harpsichord and the flute - I quite like that!

I like your use of a church bell in the coda (at 4:29), reminds me of my own, old remix of the same SID. 😉

Overall, lots to like here, some things need refinement, but for a first remix - you should be really proud of it!
