Hi, it looks good so far. For what do you need help?
May do some less monks and some more spells.
May add some cantrips, carddraw and card selection.
If you stay with the budget land base may add some evolving wilds as well.
Deflecting palm used to be a sideboard card and may you don't need ojutai for this (he is cool but he isn't a monk and he isn't an instant nor a sorcery).
If you want to play heavy with this jeskai ascendency, may do 4 of it and if you can afford it play with 4 monastery mentor, go wide and make the prowess-kill.
Soulfire grandmaster would work pretty well with serra ascendant.
You can add the wanderer (or using the boros charm) and put in some sweeper as deafening clarion. Imagine how much life it would be with the grandmaster.

What spells do you suggest to add cantrips, card draw and card selection?
I don't really know what lands go with a 3 color deck to have mana consistently. I love your suggestion with
monastery mentor, definitely will buy a stack in the future along with ascendancy.
