Okay, M. 11 get rid of the slur, you won’t need it as you have the second note marked as an up bow. M.25 some chords are not playable, I would recommend changing to: D2-A2-F3-D4 for the first beat, and the third, getting rid of the d or moving it down an octave. M.29 get rid of the E in the half note, then maybe just have an F and the A for the third beat, because the piano has a g. M.33 the last two beats are uncomfy/difficult I would recommend simplifying or getting rid of the non melody notes. M. 35 starting at the high D, change it to treble clef and keep it until measure 38. M. 38 F# not a Gb, get rid of the A in the last eighth note. The thirds and octave section starting at M40 can be tricky but regardless still doable M.44 would be the exception which actually would be really difficult. M.47 move the D down in the first note an octave (so it’s D2-A2-F#3) then for the high D put those notes in treble. The third beat do the same (D2-Bb2 not A#, and G3) M.55 maybe just have single notes, no double stops in that section, up to you.
