Thanks for the feedback!
Now, please forgive me, as, as I said, I'm really new at this....
Variation on the percussion line I understand and can do. Some bass drum would be welcome, cymbals... I'll think about that. I don't want too much harsh metal noise in there. And by the high brass, did you just mean from 0:17 to 0:29 ("trumpet"), or the horn part ("English horn") through the whole thing?
Odd that you said there was too much Charge and not enough Wily. From a purely source material perspective it's about 60/40. Melody-wise, from 1:23 to 2:39 is purely Wily, and most of the rest is either mixed harmony or not much like either source. The electric piano is from Charge Man and the bass line is from Wily.
I agree that the tuba is a bit weird, but it's hard to be faithful to Charge Man without it or something like it. I'll think that over, and maybe someone else will have a helpful suggestion.
