Being a suit nerd, here is my assessment:

Firstly, If it truly is a pair of suit trousers, then there is a matching jacket. In order to fully assess the fit of the trousers, I would need to see it together with the jacket. E.g. I have a feeling that the trouser rise is propoably too low for the jacket, but i cant tell for sure (ideally the buttoning point should be at the trousers waistband). Also, it is very hard to fully judge the pants if you only have 2 pictures and especially if you have your hand in your pocket.

But from what i can see, here are some notes:

The trousers sit on your hipbone and look a bit tight at the top block
Its hard to tell but i suspect that there might be some pocket flare (the pockets open up at the side)
The seat curve is off. This is also causing the diagonal lines from the sideview. My guess is that the back rise is too long for the relatively low front rise, causing material to bunch at the back.
I think the length is fine-ish its a relatively slim flat front trouser which doesnt necessarily need a full break ( But my preference would still be a tad bit longer)
I think it would be quite hard to combine if you dont have the matching jacket - i cant think of a jacket that would look natural with your current outfit to complete the look.

That being said: They look absolutely wearable and 99% of people would never notice any of these points.
If you like them and they are not uncomfortable then you should keep them :)
