I was hopping to get a Feedback from someone who understands about acoustics, so I can understand if what I am doing is correct.

Hello Tiago. Welcome to the bbs. Well, first off is that a rendering? If so, what did you use to render it? Regardless..nice.
Ok, first thoughts are..
I'm assuming you don't need to worry about sound transmission to the outside, no? If you do...full stop. Let me know before proceeding with "treatment".
If not, then you only have three things to deal with. The rooms LxW dimensions, the..ahem.."sealing".. and the glass. Here is why.
1. Square rooms are the worst case scenario for modal response of the room itself due to the same dimension in both length and width. They will reinforce the same wavelength reflections in relationship to the dimension.
2. In order to tame these reflections, it will take serious bass trapping in all four corners. and a huge amount of absorption, in front of the glass. In fact, in my opinion..a good majority of the glass would need absorption over it.
3. mjbphotos is correct. You will need bass traps in the corners, and considering the "ceiling" is angled opposite of what good studio design dictates, you will need a large/deep absorption above the mix position as well. However I am wondering something. Your picture shows what appears to be a "hip" roof style, whereby the area to the right side of your mixing position is angled downward as well. Is there another "hip" on the opposite side? If not, this creates a "non-symmetrical" ceiling. This may require some asymmetrical absorption as well.
In any case, you have a very difficult scenario to deal with, given all the glass, reverse ceiling slope, with possible single hip, and square room geometry. Sorry for the bad news, but given enough treatment, correctly placed, it may be possible to somewhat tame the room response to achieve fairly good results. However..it won't be cheap by any means.
And btw...you don't have a "cubic" room. If you did..I would suggest forgetting it. Unless you have very deep pockets.
I don't have time at the moment, but I'll be back with some illustrations.
ps. My opinion is exactly that. An opinion. My disclaimer remains in full force...ie..I'm no expert although I know enough to get me in trouble.
