I work as a bespoke tailor in London, England. Overall the suit looks great and the bits and bobs to change really depend on how much you paid. If you have paid $2000 for it then you need to have a word with your tailor. If under $500 bucks then is really fine.
Things to change or alter dependent on budget if not using same tailor that made it.
1. Rotate sleeves 3/8" forward - this should clear up those diagonal lines
2. Let out centre back seam 1/2" from just under collar to bottom of shoulder blades - the jacket is too tight across the arms. Point to point (across shoulder area) can't be increased as there will be no fabric so letting out back seam only option.
3. Left sleeve needs lengthening by 1/2" and right by 5/8".
4. Lower the back waistband 1/2" minimum or 3/4" max - this will clear up the lines on the trouser legs. The lines are due to you being a little hips forward which I am as well and do this alteration to clean up my past trousers that have this problem. The fit generally on the trouser is looking good forme but I am of the more trim continental persuasion.
