Brenda,
Don't be disappointed, finishing takes a while to master, It is actually a trade ion Aust with a 4 year apprenticeship.
Using pressure pac cans( I am assuming this is what you used) requires a little practice. Not to close as you flood the piece and risk runs, to far away and you get over spray eg some of the contents dries prior to hitting the piece and makes the finish feel rough and flat. For a piece like yours above I would lay it flat on a bench, ( Place a piece of timber on the bench first with a few nails through it facing up so that your piece can sit on the nail points) then give it a "wet coat" turning it a few times. When dry cut back with 240 -320 paper and give it another wet coat.
Remembering that the finish is only as good as the preparation. So before any finish is applied, sand up to 240 -320 grit paper making the timber as smooth and scratch free as possible.
Hope you can make head or tail out of this.
Cheers
