The casual shot looks just fine.

However I'm in agreement with Dave on this one the hat and the tie need to go and the jacket should be un buttoned. Choose a plain tie from a colour in your tartan. Plain red or green.

two other small things Your ghilles seem to climb too far up your legs. Try keeping them lower.Also I like to see the ghilles tied in a bow on the outside sides of the leg. There's nothing wrong it's just how I like to tie them
