Hi, I quickly thought about it but I dropped the idea a few hours later since I'm not a drawer and as I didn't found on the web neither screenshoted ingame enough convincing graphic materials to have any chance to produce anything correct.
I thought to use Delving Hills as starting base, then replace hobbits elements by beorning elements.
This would have saved me a lot of time instead starting from 0, but even this shortcut would had took much more time that I wished to spend on.
Finally, all I did is recoloring the default Lotro UI main toolbar and planting a few crops from the Beorn's farm on it
Then I released the aborted project as a simple toolbar variation for Delving Hills : "
Delving Hills Large II" profile (as these crops are common with hobbits crops).
