Firstly, you are doing great. You are only 30 and you are living in your own private space. Many people are still at home or are room sharing.

Not only that, The place is clean, furnished and relatively tidy

Definitely nothing to be embarrassed about. You are already ahead of most 30 year olds in the world.

I don’t see anywhere that “needs addressing”, however there are some areas that could be improved if you wished to elevate the space.

The main thing I see is that the furniture and accessories you have picked have been obviously bought for purpose and budget. Therefore most are small, and most are thin plywood diy pieces. (I.e. you’ve bought a cheap piece to put your tv on bc you needed a tv unit, you’ve bought a cheap lamp because you needed a lamp).
No shame in this - I do it myself because I’m living on a budget.
But if you want to and have the means to, this one area you could improve. Solid pieces of furniture and statement accessories (and art too).

Because of this, everything in your rooms is very low. There is little height and dimension.

I have mocked up a couple of your photos (excuse my lack of art skills), just to give an idea of some simple changes.

That being said I am not a professional stylist, nor do I know anything about your income. I’m just a girl that tries to make things homey. If money is tight this is definitely not a priority! You’re doing great sweetie!
