How can I better blend this logo into the background?

I don’t know any code or anything. I like the logo. It’s me by the way. Lol
But I don’t think it blends because the background is white. It just looks like I pasted it there! I wish it were bigger, but when I make it bigger it makes the header bigger, which I don’t want. Also, making it bigger makes the lack of blending even more obvious. So I am fine with the size. Anyone that can guide me on ideas for blending? Editing outside of WordPress maybe?

Oh and on my phone if I view the full website, the logo throws the header out of wack. But if I view the mobile site, it looks perfect. I guess I shouldn’t worry about it, right? Sense most people that view on their phones will most likely look at the mobile site anyway. Thoughts!
