( Totally forgot that I'd made a third Dragongirl Wrinry drawing which wasn't uploaded with the others! )
Having spent practically all her life as a dragon, Wrinry is not used to having people look down at her. The fact that her imperfect human form resembles a young girl does not help matters. While she is not usually very self-conscious, being treated like a little kid after a lifetime of being respected for her fearsome appearance does not sit well for the diminutive dragongirl. However, her disarming appearance does have the advantage of causing her enemies to underestimate her strength, despite the draconian appendages. The fake human body, while appearing soft, is nearly as resilient as her limbs.
Additionally, her small appearance belays her weight, which, while reduced, is still several times that of a normal girl. This leads to many issues involving property damage from sitting or standing on things not designed to take the weight of a small dragon.
