Pan fried venison leg steak and lamb's liver

Tesco, where I order regularly for delivery, has recently added new products to their shelves. Among them are fresh counter sea bass and venison leg steaks. Seeing as it was my first time cooking venison steaks, I decided to keep it simple and pan fry them with some butter for dinner. I also pan fried some lamb's liver in butter and, in a separate pan, baby potato slices in duck fat.
