Thanks so much for your support, Bessiere and Gunnar.

Very nice and a realistic touch. Anyone one of these figures would be challenging to convert to the standards you do but an over 20 -piece band?...
Bessiere, the truth is, when I started this project almost a year ago, I had no idea how far I'd be able to go. Although, knowing my penchant for perfection, I could imagine I'd make it more complicated than necessary, haha.
In fact, the band will include not just one, but up to four female musicians. Studying the proportion of both genders in the actual band, I believe my proportion of 4 in 24 is quite accurate.
Just yesterday, I took these photos at the concert offered by the Royal Guard Music Unit after the solemn changing of the guard at the Royal Palace in Madrid. Considering that the concert was very short due to the high temperatures (around 36ºC at 12 noon) and that only a fraction of the band's 100 musicians participated, I was able to count up to four women out of the approximately 35 or 40 soldiers who appear in the pictures.

I've tried to make the instruments my female musicians play match reality. Thus, the first is one of the two clarinet players already posted on the forum. The third and fourth will be one of the three drummers and one of the two saxophone players.
To achieve the second one, I had to make a small modification to an already finished figure. I added a bun to my flute player, and voilà, I have a woman. Here are the initial and final figures, see if you can tell the difference.

Best regards and stay safe from the scorching heatwave sweeping across Europe, my friends!
Santi.
