Boxy, irregular room - ideas for treatment?

I just moved to a house in Montenegro where I plan on putting together some video guitar lessons. I am trying to live cheaply over the next year or so while I get my lessons produced and online. So I am in a house that does not have ideal space. I put together the attached 3D diagram (to scale) to show you the space. The main area is fairly boxy, but with some irregularities. The walls are actually somewhat slanted so that it is not quite as boxy as my diagram looks, but nonetheless fairly boxy. About 2.8m x 2.8m. About 2.25 m tall. And there is this entry way shown as well, which might cause problems with stereo imaging.

Walls are concrete, floor is some sort of hard tile. There are these cavities built into the walls that I suppose can be used for storing some items, and maybe will also help with standing waves (but maybe hurt imaging). My current plan is as follows:

1. Carpet the floor
2. To create some angles, place two diffusers (or whatever to call them) behind desk to right and left.
3. To right and left of sitting position place absorbers (each about 1 m wide, maybe 1.5 meters tall, 1cm plywood with rockwool and canvas)
4. On ceiling between sitting position and speakers, place another absorber, about 150cm x 60cm
5. On every wall surface on rear half of studio, including in the entry area place absorbers from ground to ceiling.

Maybe it is a lost cause and this room will really suck... But above is based on some advice of someone I talked to recently who has built studios in the past.

I don't need to do anything very complex. Just my guitar lessons, plus recording my compositions with sequenced backing tracks and of course the mixing entailed with that. Maybe some film scoring work (not mixing - scoring). So a decent environment will be good enough, and if it borders on really decent then that is a plus!

I am buying everything at local construction stores.

Any ideas?

Thanks!

Square room, and concrete, you're going to have a tough time getting anything but 'boxy'. I'd forget diffusors in a room that size (read the 'small room acoustics sticky here), and just put as much rockwool trapping as you can squeeze in.

Don't rush to carpet the floor, ceiling clouds work better and you can have a rug or 2 that can be rolled up if required for the sound you want. The square room is hard to fix, but if thats what you have, bass traps is what you need most. The room however is small so the space the bass traps take up could be a problem. Try having a look at bass trap design that also double as broadband absorbers. Have a read here. You could also chunk the corners between the wall and ceiling.
