Ruji,
It's impossible to give you a personal answer, since I don't know anything about you, your art, or what your goals are. So let me address the broader question of finish.
Finish is a very subjective quality in a painting. One artist may want to make the painting appear like an illusion of reality. To that artist, a painting is finished when the illusion betrays no visible brushstrokes. Another artist, wishing to preserve the energy and dynamics of the surface, may regard a work as finished with a lot of loose brushstrokes preserved.
But both of those qualities are superficial. Finish is more than facture. What really matters in making a work finished is whether your inner conception is fully realized. Does it communicate the feeling you wanted? Is it convincing, disturbing, exciting, restful, or compelling?
If not—if it's sort of ordinary looking—it may be that your problem is not how the painting was finished, but how it was started. Maybe you need to spend more time in the early stages sketching and planning the work, getting the reference lined up, and knowing exactly where you're headed. The resulting painting may still take some struggle to be born, but hopefully with that preliminary work accomplished, the final painting will come together and it will tell you when it's done.

Charcoal study by Sargent for "Heaven" mural
in the Boston Public Library.
Efficient, concise, and a means to an end. |
You also mentioned that you can never seem to make your gesture sketches look finished, either. That seems like a contradiction in terms. Isn't a sketch unfinished by definition? We owe this predicament to our contemporary art culture, which makes a fetish of the sketch, and elevates preliminary studies as completed works worthy of exhibition. We've all seen those drawings from contemporary ateliers that are very laborious, but deliberately leave a foot or an arm in the linear construct stage, which strikes me the same as a carpenter leaving the clapboards off one side of the house.
If you're doing a preliminary study, move fast, capture the essentials, and leave it. Like the study by Sargent above, a study should be a means to an end, not an end in itself.
There's nothing wrong with exhibiting your sketches, but I would caution against being overly conscious of making "sketchy" gestures, and instead focus on capturing as much truth of nature as you can in the time available and let the strokes land where they may.
