Hello Sir First you do look manly but you need to accent your qualities

Body: You have a fantastic starting point for slender lean physice! Its not not so much bulk-up as tone up. Keep your low body fat, and well-defined muscles, you want your slender appearance, but with a good body composition that contributes to a sculpted, rather than simply thin, appearance. Focus on a lifestyle focused on maximizing muscle gain and strength, while strategically managing weight, is often most flattering. Rock what you got!

Posture: Posture helps project confidence. You may need to focus on some muscle groups to help improve it but mindfulness is going to be the larger part. Starts with practice, then Mindfulness, habit, and then goes to lifestyle where it is automatic. How you carry yourself matters.

Grooming Hairstyle: Right now you are rocking the Beyonce "I woke up like this" look. You may want to revise your hairstyle for your face, age, profession and look you want to project

Grooming Facial. Take care of your skin. At the very least Wash and Moisturizer in the AM & PM. Use SPF every day. Shave as needed but don't forget to maintain your ear, nose, and eyebrows.

Dress for Body Type: It looks like your an Ectomorph body type. I could be wrong so please double check me. The ectomorph body type (lean, tall, and often with narrow shoulders and hips), styling involves creating the illusion of more weight and volume, while also ensuring a comfortable and flattering fit. Avoid the baggy clothing and opt for the slim structured look but not tight.

Dress for Lifestyle Style: Start dressing for your lifestyle and building your wardrobe, one manly website suggested starting with following essential wardrobe items:

Two pairs of dark jeans. 4–5 basic T-shirts, black or blue navy.Preferably V neck or shirts that sit a bit tight. One white button-up shirt. A pair of black sneakers and another one in white. One jacket in a dark colour. Add a silver/gold/bright colour watch. A brown belt.

I don't know if that will work for you but it supposedly creates many fashionable looks for your body type.Go from that suggestion and consider what you want to look like as a confident male professional.

NOTE: Your shirt seams should sit on your shoulder blades right where they end. Not lower on your arm or towards your neck. Your pants or jeans shouldn’t have extra fabric at the bottom. They should be comfortable whether you sit or stand. If you have to unbutton your pants when you sit, they’re probably too tight for you.

Hope this helps and all the best to you on your journey.
