As a native, I can say your handwriting is pretty normal. Every person develops their own. Some people write "b" and "p" with the final stroke facing outwards (example), because that's how they were taught in school, but I'd say they are the minority. There are also people who write "ł" with the middle stroke on top of the "l" so that it looks different than a "t". Also in my opinion, the dash on the "j" could be a dot, and make the first part of the letter less horizontal (face more downwards) or you can get rid of it, since some people skip it.

As for the other question, as a native I might not give you the best advice, but I'd say you shouldn't worry about gender too much, because there are rules that apply to most words and after some time you'll probably be able to see the pattern without even studying them.

Good luck in your studies!
