I think all the figure is very well painted, I like the heraldry ( fine drawing) and metals as others said, and also the ground is very well done . The transitions, textures and skin tones are masterfully done. Nice figure in 75mm.
This is a really nice figure and your paintjob is the best I've seen it look
A couple of historical points on the heraldry: it's just beautifully painted with lovely crisp edges but I believe this style arose in the late 20th century (60s I think)! Also the painted shading, if it's intended to show how the charge was painted originally, I think the lighting angle should be from the top of the shield.
And on the arrows, not sure if they come with the kit but if they're supposed to be European longbow arrows they would have three or four fletchings, and they would normally be set quite a bit forward from the end of the shaft.
