Hey racnos, i like the concept and the idea you got in this design! i alos like the connection with the spikes, on the headpiece and on the wings, its always good to repeat a design on a character so that it doesnt look random! my only thought on this is, the wings, can she fly? if yes how? if no, i would suggest to maybe resize some of them that it doesnt look symetrical but keep the balancing! just that the viewer gets a clear vision what the wings are for
cheers
