You've got me curious, I'd like to see what this, the rose, becomes over time. If it were mine, you are done with pruning until spring 2021. Let it grow out, harden off, and over winter it with minimal protection. Ideally, it gets buried in snow. Or park it in a cold frame. You might want to protect it from temperatures below maybe +10 F, or -12 C. That ideally would preserve as much as possible of the trunks & roots.
In spring, as soon as you can tell live from dead, prune to style the tree. Prune away what has died. Then let it grow out to bloom and form the hips which will be the Autumn feature. Rose bonsai are cut back hard every spring, to style. Then allowed to go wild the rest of the year. Keep your trunk, leave short extensions of branches every spring. Let them grow all summer. Leave canes long through winter, the long canes, even the dead ones, draw moisture away from the trunk and help prevent the "crown" from rotting over winter. Spring, the cycle starts over, prune everything to just a small addition to the year previous, and then let it grow wild.
