<human>: Can you condense the text into a few key points?

Hi! Thanks for providing me with some guidance. I do not have a lot of weight I want to lose, more so I want to improve my overall physique and fitness level. I am currently F/5'8 and 139lbs. I would like to be and look fitter, so I am currently working on losing weight and increasing exercise. Right now I am eating at a calorie deficit, but I really don't know at what weight I should switch from calorie deficit to calorie maintenance+increase workout (to build more muscle). For example if I reach 135lbs but still am not satisfied with my figure, should I keep focusing on weight loss or instead focus on building muscle? Is it better to reach a slightly smaller weight like 130lbs eating at a deficit, and then switch to maintenance+increase workout in order to gain back a couple lbs in muscle? The issue is I don't really have a goal weight, more a goal body, so I don't know what weight I should reach before switching from deficit to maintenance.
<bot>: I don't have a lot of weight to lose nor a specific goal weight as I'm more concerned with a goal body. I am confused on how to balance calorie deficit with calorie maintenance+increased exercise in order to improve physique.
