What I look for mostly as a judge (in a rough descending order of importance):

- Sync. This is a critical element of charting. You must properly align the notes to the music, which means you have to use correct bpms and offset.

- Consistency. The charting decisions you make throughout the song should be consistent. When you break that consistency, you must have an explicit reason to justify doing so. For example, you chart a buzz noise with 48ths rolls everywhere but one buzz you did a jumptrill. If there is justification from the song like the buzz is different enough or you layer something else for other justifiable reasons, then it's probably fine.

- Representation. The chart should reflect the song. There are often many many ways to achieve this, but some ways are more intuitive than others. You can have a lot of consistency and good sync, but if you charted the intense parts of a song as the easiest section of a chart, usually you'll get confused looks from people.

- Balance. The chart should have a justifiable difficulty curve. While spikes are fine in certain contexts, if you fail to justify the existence of a massive difficulty spike/increase in your chart, chances are you'd probably want to rethink it.

- Originality. A chart can have all of the above but still be super bland. Sometimes there's nothing wrong with it if the representation aspect is already pretty good given the song, but if people deem it to have a fair amount of leeway to add variety without sacrificing other important aspects, they may suggest it.


I hope this helps you and good luck with your first charts! Keep in mind that 99% of people are pretty bad the first time around, and then it gets better once they get a feel for the techniques used and what people like to play. ^^
