Winged hussar horse - progress sketch

Salve,
days are getting shorter and there seems to be more time to spend engaging in digital painting, so I would like to share a progress sketch of a horse in a winged hussar horse tack (as used in Polish-Lithuanian Commonwealth), including a wing attached to the cantle, 'koncerz' ( 'piercing sword' or tuck) under the Old Poland saddle's skirt and wild cat pelt/skin underneath the saddle instead of shabraque...
     I have several version of this iamge, so hopefully will show them all here in due time.
I used Gimp and MyPaint to get this far :)
