I need help with making this not look terrible because to me it's absolutely terrible. 

This is a slightly older picture but this is the most I did to my setup. The red lighting pic was the most current but hard to look at so I added the other one. 

Besides the wall stuff *which I have taken down*, why does it look so bad? I have an IKEA desktop that's around 63" or something wide, 31" deep. I am planning on buying cable management things such as a tray and clips, but even if they were more squared away I really don't see it improving much. The plants look dumb. The little tiny cabinet looks dumb. Not sure what I should *actually* put on the walls or on the desk. 

I'm planning on getting Alex drawers on both sides so there's more to the desk, and I want to hide my PC near the wall so I have more space on the desk itself. But overall, I want a more productive looking desk and not gamery at all. I want to add wood to it so it has that natural coloring going on, but the only thing I can think of is a little monitor riser stand that's made out of wood but it wouldn't match anything else. I'm starting online school full time and want something I can be working at for long hours during the day. 

Should I just get a new tabletop that's wood? or an entire new desk lol. I see so many nice setups here and over at battlestations and I just don't know how to make my own. Y'all are truly talented people. Thank you for any help. 

How can I improve this setup?
