Richard,

A good first BIAB post.

A few suggestions...

The vocal is a bit "too up front" - dominating the mix. You want it to be "tucked in" a bit more. To do that, bring the volume down (in Studio One) some - start with about 2 dB for the whole track - it might take 3 dB... you might also add some more reverb to it. If you are using one of the Studio One reverbs (they are very good), just turn the "mix" knob up a little.

The drums could be a bit louder in the mix. Maybe 2 dB.

The piano and bass sound good they are at the right level.

Your harmonies on this are well done...
