Ive been working on this for the last few days. i know its not polished but still im quite happy with it. just have done a basic intro into a verse and then a breakdown. trying to think how to expand this out a bit more. https://soundcloud.com/mark-shevlin/jelly
IMHO you've got all necessary elements to make a full track, so I do believe it's more a matter of arrangement and probably subtracting elements to create parts & progression rather than adding new elements.
