i mean you dont even have to rig it, a pointless step, just deform by hand
how many different poses does it need, two other ones?
Of that quality you can make it all in zbrush or mudbox, both allow for simple renders and both have better sculpting bad texturing tools ( except zbrush, zbrush texturing tools are shit), but the workflow would be the same
render out, what 4 renders for each pose? 12 of them? then take into photoshop, adjust resolution, paint up some glowy bits or delete pixels that ruin the silhouette, fuck around with saturation and values, or dont
and you are done
