try to take pics when its warmer out or in a public place inside like a bigger mall or something like that where you are walking. Or a picture I love is a cooking or grilling pic. lastly the pouring wine picture seems to work out well too. Having a bunch of pics with coats on is not going to be super flattering (1 is fine).

In general your style is pretty good for someone in their early 20s (trying adding some more dark tones like dark gray, black and navy for shirts) but I would work on getting more cut in the gym. I am guessing you are probably 15-17% body fat and your arms and core will be a lot more cut at 8%-12%. However I will call out that I think 8% body fat is pretty tough for most people to maintain long term so just getting to 10-12% will go a long way.

Take some more pics and we can give more feedback.

yes that sounds like a good spot. Try getting pics of your sitting but appear to be candid and not posed and also try to get maybe some of you doing an activity. If you have a friend with a dog then bring them to the park and play with them while taking pics.

Then when girls ask you about the dog say it's your friend's dog but you dog sit for it all the time and your basically its second dad and they won't question it at all.
