What is the soul in the picture?

I tried using watercolors on postcards, but they seem to be paintings, and I feel that something is different.

Drawing a lot of this is just crap.

So I don't draw them anymore.

They have no soul.

It's just a suggestion.

These are decent finishes, but it was even better when I was drawing similar paintings in the past.

There is not enough inspiration for these.

slump?
