Pretty damn good. I love how you managed to make the textures and shadowing 
Thank you. There is not a lot of texture on the H plate because I didn't deem it necessary - it's just gold to me. I did try to copy the reference as closely as I was able to, but there are noticeable differences...and one of those is the lion. The way I had drawn the outline of the shield kept me from being able to 'copy' the lion, so I worked with what I had and made a similar (though thinner) one.
Thank you for your input!
Good textures. Why not in / around the H too?
The lion griffin might be too small, and lacks contrast.
Did you use a reference? Please provide link in case.
Very good!
