I opened your image in ACR and in the 'Transform Tool' section, I selected the 'Guided' tool in the 'Upright' section on the right. I used two vertical and then two horizontal lines which got me 95% there. After I got back to PS, I opened the image in ACR a 2nd time and used the 'Auto' alignment tool for the remaining correction.
I have the grid lines on in the Transform window but wish I could change their color to separate them from the image more. I have DxO ViewPoint2 but for me, the tools in ACR work best.
And, I think your angled abstract is an even more powerful version as well.

Great job Gene. You got a lot closer than I did. Thank you for sharing that.
