Love the long lapel I have a suit like that in black, not loving the two toned belt and the color combination is too netural for my liking but it works with your color tones and lastly overall it's really good.
personally, i don't like the double-toned belt, the trousers look to baggy near the shoe and don't really like the shoes. but man, your style and personal taste should be over any opinion ;)
id have to say a miss myself if it was for something as important as a networking introductory to the industry night. I get that mature artist struggling to survive vibe from your pics which can work for you...if your johnny dep. Blazer wasn't showcasing much like slim build and shoulders, looked to be more covering up things. Might have done better with a sweater maybe with that mandarin collar. That would have made the belt become a feature. I see some nice black shoes in your pile. Pants are loose but you can carry that as comfy. I just think the blazer's letting you down.
that my 2 cents. take what you want from it and ignore the rest..ha
