Need groom suit advice please.

The first picture is the suit I'm wearing for my upcoming wedding.

The second is a pair of brown shoes I already own and the third is a pair I'm thinking of buying.

My question is

A) would i get away with my current pair to help out on budget. They've only been worn twice but do have some creasing etc.

B) do the second pair suit the overall look better than the first?

C) is there a different colour and style altogether that you would suggest?

I don't have many people to lean on in terms of advice so any help would be appreciated.

Thank you.
