Make my beam look better

How can I make this look a little better? Should I caulk or trim out the gaps on the tap due to the bow in sheetrock? Also on the end, i was thinking about buying some powder coated joining plates to go on all three sides on the end to help hide the joint. What do you think. FYI I'm not a carpenter. I originally wrapped this in plywood and painted it white 5 years ago and always hated it. I changed that post to a solid 8x8 sawn post and then trimmed the lvls with rough sawn boards. Let me know what you think I should/ can do. Thanks.
