I appreciate the way you combine patterns, texture, and colors together. I think those are all spot on in this composition except the pocket square and socks. I think something in the blue or brown family would have worked better. The biggest issue I have with the outfit is the jacket. In particular, the balance of the jacket and the large v it creates. It seems to be a fairly large collar gap at your left collar. I think the lapels need to be rolled to the top button. I wouldn't recommend buttoning the top button, but I think this would make the lapels sit closer to your collar and eliminate the gap.
The wide lapels make you broad(er) and toss the balance about. It is very good, very close, but skinny guys wear these wide looks to create more substance. Your waist is narrower, and with those lapels at the top, looks like you might fall over.
