I've never seen such thing before. It's really amazing. The shading, the clouds, and I can tell you tried really hard.
The originality is really good, but I still think there are some drawings out there that have the same idea; bird in harpy arms
Technique is really cool. Shading is well done. Light source is all correct. The clouds may seem a bit strange, but it brings interest.
The hands of the harpy are really detailed. I can see how it took a long time to shade each and every scale and side of it.
Overall, This is very impressive. I'd really love to see more work from you Bandaid Keep up the amazing work
