"I already sent this pic to Ethan Winer a while ago via email (hi, Ethan

), when I was planning a RealTraps purchase. I got some good pointers from Ethan. I however decided that RealTraps were too much for my wallet, especially because of overseas shipping, so I went the DIY way."
Well if nothing else I hope you offered him some kind of payment for his personal time he spent helping you.
"I'm considering making even more traps at some point and placing them to wall-ceiling corners, but I'm hoping to get other ideas here. Another listening position perhaps? I've experimented a little already (a a foot towards the front, towards the back, towards the right), but it isn't really helping. The overall flattest response has been at the position shown in the picture."
Sounds like to me you just need to keep adding more bass traps in the room. Not sure where you have all the traps now, but cover floor to ceiling in all wall to wall corners and at that point start to cover ceiling to wall corners. Also you may want to place a couple traps on the back wall. How did you make the traps?
BTW your room set up looks fine also.
