How often do you do water changes on your aquarium? Do you spot clean regularly to remove visible waste? I can't tell if your tank is done cycling or just starting. You have detectable ammonia, but no nitrite. In the cycling process ammonia appears first, then nitrite and finally nitrate.
If your tank is just beginning to cycle than it is quite important for you to watch the water quality and to do partial water changes when the levels get high. I would watch your water quality and if your ammonia or nitrite levels ever start climbing make sure to perform a partial water change.
Your nitrate is a little high, but not too bad. This is the least dangerous chemical in the cycling process and will always accumulate as the toxic ammonia and nitrite are converted to nitrate. Nitrate also appears in tap water on occasion.
