Tell me where I can improve my profile

It's an ok basic profile but I would take out the last line of your write up. Saying if you want to know more just message me means nothing to a potential match. They will message you regardless if you have that in your profile so it does not add to the profile's importance.

Your listed interests are outdoors. Your profile only talks about being indoors. Your main photo shows you in some warehouse-like building. Have a think about what a woman is looking for when she sees your picture, looks at your listed interests, then reads your text. While none of us are just one-sided, it would help to concentrate on what you are portraying of yourself. If you're a homely guy, a photo of you at home as your main picture would help; if you are an outdoor man, a photo of you outdoors would be best as your main picture.

The photo with someone else I would remove. I think it's always dodgy to include someone else and can be viewed as a sign of disrespect, even if they are family.
