A kobold, or at least likely to be of that race given the stature, shape, and general scaled flesh of this creature.  Given the nature of reptilian anatomy, the gender at a glance isn't obvious, though the style of dress suggests it would be female.

 She - it's simplest to lable her so at this point - stands at a height of four feet.  The frame is lean overall, though there is some curve to the thighs and hips.  The flesh covered in small green scales that are largely smooth to the touch, bumpy rather than ridged, except for at her head.
 That head has thicker scales, crowned with mottled horns, and often adorned by an ornate winged crown.

 Without any trace of mammalian blood, this creature, unsurprisingly, lacks identifiable breasts that would have cemented the gender visually.  The underlying muscles at her chest, along with a pair of darker hued patches to her scales, do give the impression of small breasts to any that see her shirtless.

 Hands and feet end in clawed talons.  Those sharp talons offering firm perch on all but smoothed stone and metals.  Those, mixed with those heavier thighs and hips, and that slender kobold tail she bore combined to give her a stable base of balance, and add fluidity to her motions.
