Looking for Suggestions - DIY Sound Treatment for 2nd Bedroom

First off - sorry for the long post, but I'm hoping someone with experience can provide some insight...

I've finally decided to put some money into treating my mix room. I've held off - mainly because I'm renting and know I will be moving, but after some thought have decided to build some bass traps that are sturdy enough to take with me when I go. I bought 2 6-packs of OC703 and started making plans on what to build and where to place them, but before I dive in I thought I'd see what the GS world thinks.

About the room - 105"x128"x88" - Basic dry wall and hard wood floor
If Wall A is the wall in front of the listening position and the rest are named clockwise...
Wall A has a window about 16" from the corner of Wall B
Wall B has a closet about midway and a door in the corner of Wall B/C
Wall C is blank
Wall D has a window midway

My plan right now is to build 12"x12"x16.9" triangular (or super chunk) corner traps to go floor-to-ceiling in the two corners of Wall A (I would do 24"x24"x33.9" but I have the window in the corner).

After that I can do 6 2'x2'x4" squares to place on the walls - probably 3 turned on their sides (diamond-like) across the wall behind the listener and I could place the others on the remaining walls. Or I could place one additional on the wall and make one 2'x4'x4" panel to hang from the ceiling.

I've seen some threads out there about building these traps and placing them, but realize every room is different and am hoping that some folks could provide some insight based on their experience/knowledge. Thanks!

No worries. Same old story for anyone starting out, multiply what you are considering by four then multiply that by four again..... The smaller Studiotips SuperChunk is really disappointing in my experience, while the large one is great. Consider different shapes, square or rectangular, like SoffiTraps.
You will need to eliminate early reflections at the mirror points. At both sides and over head. This will take at least six 2'x4'x4" traps. I don't think anything under four inches is worth the frame.
etc. etc. do you best and go for more as soon as you can.
Here's a great DIY trap design by a client of mine. Another client used six inch duct with four inch fibre to include the air gap.

Yeah, agreed with DanDan. If you have a limited amount of material, 4" thick panels seem to be the sweet spot for cost-effectiveness probably because you can maximize coverage area. If you can cover all the surfaces you need to (all 12 corners, reflection points, rear wall) and have more material, then start making the panels thicker.

Thanks for the advice! I've considered just making panels for the corners, but have also read that using flat panels in corners requires a large room so that the panels can be pulled away from the wall. I don't have a lot of space to work with, but I could fill the two corners with 4" panels (1 2'x4' and 2'x40" each corner) and that would leave me with 4 2'x4' panels I could use to make additional traps. Maybe 1 2x4 above listening position and 2 2x2's for the side walls? Would that make sense for the corners? Thanks!

For DIY I generally opt for 2'x4' panels all the way around, mostly so I don't have to deal with cutting fiberglass or rockwool. But sure, make them smaller if you need to do so to fit them in place. Just remember coverage area in the room is just as important as the thickness of each trap, arguably more so.

In canada we can only easily get the 3" safe and sound. Should I do a 4" deep frame which would include a 1" air gap or go for 6" deep traps with no air gap? Not a lot of options..

If it was up to me I'd say go 6" if budget supports it.

Budget is not a problem, it's just that 6" just starts to take a lot of real estate. Currently my options will be either 6" of SnS or 4" of OFI-48 (basically oc703) if I can source it, there is a possibility in town.
