I would suggest cutting a few spells or making some of them 4 ofs for consistency, also something like
monastery swiftspear for more early creatures to attack with. Maybe even
young pyromancer. I would also add a couple of
bedlam revelers with the amount of early spells you will be casting, reveler shouldn’t cost more than 3 max. Also jeskai ascendency is a house and is really powerful however it will slow you down a bit but it may be worth it. Personally I love jeskai brews like this and your deck seems legit. It just needs a bit more oomph to finish off games quickly.
