Along with some of the various issues the other gents here have identified, the chest does look a bit loose/big. Your arm that's holding your cameraphone, the bicep looks like it's pushing against the chest and pushing the chest outward. It's as if you could stick your whole fist under your jacket in that area.
Definitely take it to a tailor who will be able to see you from all angles. Indochino warned me to get an assessment on whether the tailor will be able to correct everything BEFORE actually doing the work and paying for the work. Then, if the tailor deems that your suit is grossly "unfixable", you have just cause for applying for a remake.
Since you received the suit yesterday and Indochino allows something like 14 days (or was it 7?) after receiving to apply for a remake, definitely take action sooner than later.
Best wishes, and keep us updated with your progress.
