What can I do to make this small, uneven room better for mixing?

I have a small basement room that I use to record in, and want to start doing more mixing or my own recordings.   This is the only space I have in the house that I would be able to use.  The room is fairly small, approx 3.3m x 2.8m and is basically rectangular.  The ceiling height is 2m.  Can anyone recommend any treatment/products that could help turn this into an acceptable sounding room? 

Unfortunately I can't seem to embed photos all of a sudden (if someone could that would be amazing), but a photo.is here:

The above picture explains a good basic setup. Start with the two wall absorbers and the ceiling absorber and the three absorbers on the rear wall (the wall at the bottom of the picture). Add the others as you are able.

Make sure that the tweeters (the little speakers right at the top of the monitors) are at ear level and check that the tweeters and your ears are not half way between the floor and the ceiling.

As for making or busing the absorbers, also known as acoustic traps, if you can make 1,200 x 600 mm wooden rectangles, a minimum of 10cm deep but 20 would be better, and fill them with the cheapest rolls of insulation (because it is less dense than slabs of insulation), and cover them with a breathable fabric - one which you can breathe through, like hessian or a loose-woven cotton sheet, then DIY will mean you can make all the traps for about the price of buying one ready-made trap. If you want to go the DIY route I can show you photos from when I made mine.

Things to avoid: pyramid foam, egg boxes and carpet (the rug under your chair is fine) as these are popular "soundproofing" items that will not help you. You will come across mention of diffusors but your room is too small to benefit from them.

That should get you started.

That's really helpful, thank you

Oops! That should have been: buying.

Eric Valentine has done a few good videos on setting up a space, by using measurement mics etc, in a less than ideal space.
I would be slightly concerned about the symmetry of your space, and wouldn't start out with a lot of dampening before trying to find out what effect the shape of the room is having.
Something as simple as rotating the desk slightly could have a drastic effect, and it looks promising.
The clear BC rich is as cool AF.
