Correction in terminology: Not SLS (it's too coarse for powder polymers and beam parameters and too expensive for direct metal sinthering), but SLA and similar (DLP-SLA, M-SLA). On the picture I see scale ~30mm and it's OK for DLP or MSLA. But 15mm scale would be too small even for this type of printing (if we meaning about details... detailing would be lost even with 0.025mm Z-step). I'm sure.
BUT! Anyway scaled to 15mm it would looking after printing not so bad ewen with lost small details. (at least not worst than human figurines for railway or battle modeling)
