Jaysus Andy - that's some turnaround. You've gone from looking like an OAP ASBO to a gentleman in little or no time at all! I'm impressed. (Just kidding about the OAP bit!)
My tuppence for what it's worth - On the pea coat look, I'd definitely try that with a flat cap. Think it would suit the look perfectly. The second hat in pic 3 is cool as f*ck.
On the suits, definitely get the trousers sorted. The addition of a pocket square would definitely lift the look too. And the last bit I'd add, is maybe try a slim fit blazer next time - with your build you'd definitely be able to carry it off. Also, you might try wearing the trouser waist a bit lower.
Other than that - great show dude. I wish you much continued success in your "new clothes adventures" and as Nat says in his post, I'm sure you'll soon be developing a style all of your own soon enough.
