I like how you've visualized the concept. Most technomancer art that i've seen, lean too much towards fantasy. Portraying the technomancer as some wizard tech-nerd in futuristic fashion clothing, wielding a mystified tech staff.
But this is so much better, it feel so much more real. It looks that he/she have combined the principles of science and magic, integrating it together so tightly that it have blured the lines between the two. (As if in his/her eyes - Science is magic and vice versa.) Magic is more subtle and quiet, wheras science is shameless and clanky. So it makes sense to make the machine part of technomancy more visible, otherwise it's just lookes like a co-operation between science and magic rather than a merging of the two disciplines.
This artwork makes me imagine a group of technomancers floating through space above their planet, defending it from the space fleet of the inquisition who believe that magic is a sin and the work of the devil. (They had to escape earth and terraform a new planet due to harrasment and persecution from the church.)
