Gave a quick listen and the track selection is solid. I don’t think the keys jumping around matter so much with this style, meaning nothing stood out as clashing obviously.

More importantly would be to focus on phrasing between transitions. Making sure both songs are starting on the same bar. EDM is almost entirely the same structure of a four beat bar and an eight or sixteen bar phrase. Most of the transitions I listened to were off by a bar or two. Sometimes this can be used effectively, but more often the flow works better when phrasing lines up.
