Thank you for sharing here!! Always cool to see your updates, and glad you have made it to Lemmy!
You may want to also include the post body in the Lemmy post body as well. Imagine Superstonk was taken down someday by Reddit as other subs have been? Then that link wouldn't be live - including the text body of crossposts on this Lemmy instance will help preserve it.
Seconded! A low-effort way to ensure the content is available outside of r*ddit is to use archive.is and create a persistent copy of your post. Link that here to the lemmy-verse at least until everyone moves over here properly :)
