Seeking advise for bedroom studio.

Hi guys. I'm super glad I found such a well put together and informative forum. It hit me like a brick a few weeks ago that my recordings sound like garbage because of my recording environment. (OK, at least partly because of my recording environment.) I record mostly acoustic instruments and vocals, sometimes i'll mic a guitar amp at low volume. I do it all in the middle of my bedroom, which is a symmetrical 15' by 12' with 8' ceilings. The flooring is ceramic tile, which I assume is not helping either. My original idea was to "deaden" one wall completely and use 2 corner bass traps. I have a feeling some of you guys will have brighter suggestions. My only concern is space and the fact that I have to live in this room. Here's a rough look at my room. You can see where my desk is, that's a mattress in the top left corner, dresser on the bottom. I also placed the window, closet door and entry door.

part of the problem may be your mix desk if off center. adding the corner bass trapping (or wall-ceiling corner trapping) will help as will some smaller absorbers on the front back, side walls and a cloud on the ceiling to tame reflections. don't make the room dead though so start with the corners and basic reflection point and see where you get to before adding more.

Thank you for the help. I found a good deal on some 2'x4'x4" "Fibrex" rock wool panels. Would that be a good choice for my corner and wall/ceiling corner traps? As for the other absorbers, how critical is their placement and roughly how much surface area of a 15x8' wall would need to be covered to be effective? I apologise for the nagging questions. I've been browsing the stickies and searching around quite a bit, there's just so much to soak in and i'm far from understanding the science behind this stuff. I'm just trying to make a terrible sounding room halfway decent. Thanks so much in advance for any advice you can provide.
