For now, it's just some ideas. The development of the theme is not definitive of course.
And if it sounds french, it's normal... As you may have guessed, I'm french. So it sounds like a french tango... If you say so, it must be true...
After having done polkas and waltzes I try to do a tango... I'm hearing this in my head. So I try to apply harmony rules on this (8/16 measures, chords symmetry etc.). I'm currently running in 4/4 and the key is F minor. The current theme is on 8 4/4 measures.
I'll develop it and orchestrate little by little..
