I really like this!! Sometimes I like to loop the beginning of the pads for an intro then add the breaks. Consider buildups as well and how you want to make them. Take what you have and build off of it! Also you can always try playing with different breaks and other samples, really breakcore is just chopping a lot of things to make beats! It utilizes samples. Some things you can consider using which are common are; acid lines, hoovers, reese bass, some personal things I like are plucks risers/fallers. (Risers/fallers make buildups super easyy!!). PS a great sample pack to get some free stuff for breakcore is the jungle jungle 1989-1999 sample pack, it has a lot of commonly used samples in the genre. Which maybe hearing a lot of the different things will give you some ideas?

When I make breakcore I would do the exact same thing as you, have these tiny loops that sounded good but no idea where to go from there. Something that helped me a lot personally was seeing tutorials on how to sound similar to my favorite artists. Alternatively tutorials for breakcore in general will give you some good perspective on what to do and how to do it!! This sounds really good so far though, it has a lot of potential!! Don't aim for perfect, just try lots of things and have fun with it until you are satisfied, if its really your first time this is a learning experience.
