Welcome to Hive! I just looked to see if i could find a reason for your post having been downvoted. (not this one but the other one)

I don't see any downvotes and i do see your images. The only thing i can think to be possible is if your posts were muted in the OnChainArt community. They just released new guidelines which you can check out on their pinned post.

The SketchBook community is another great place to share your art too. I really like the wood-burning technique. It's not easy and i think you captured the likeness very well! Great job. Keep plugging away at your posts and art. Consistency and quality will be recognized sooner or later.
