Help with room treatment?



I know my set up is very modest compared to some on here but I am just getting into this over the last 4 or 5 months. I built a room specifically for listening and once completed my system has sounded so much worse. Bass is worse, highs are worse. I understand it is a fairly empty room right now. After addressing first reflection points will it get any better?
Or should I return to my living room?

To add pictures best thing to do is to create a system here

This is way you can keep it updated as things evolve 

What’s the rug made of? If it’s synthetic try replacing it with a similar natural wool rug. Synthetic rugs no matter how plush or comfortable impart a harsh tone. I’ve fallen into this trap a few times

plus the suggestions from millercarbon are good, especially about getting rid of asymmetric surfaces like the stacked LPs. In my room I can hear the sound of an exposed CD case, and it’s not pleasant 🤪
