I just finished Spanish with a 58%. Is there anyway to learn more or is this the highest I can achieve?
Congrats on finishing the Spanish tree! That's something to be proud of :)
You can't get a lot higher than 58% fluent. Some courses will let you get a bit more, some probably not quite as much. Here's a post from staff explaining how fluency is calculated (but I wouldn't put too much stock in the fluency rating): https://www.duolingo.com/comment/19032758
You will learn much more Spanish words and more difficult sentences by using the "Strengthen" features.
Here is the link to "Best Way to Make Your Tree Turn Gold and Stay Gold"
Other ways you could improve your Spanish:
The reverse tree, the course English for Spanish speakers, is very useful. There you have to translate much more from English to Spanish.

Use the web version of Duolingo (http://www.duolingo.com) instead of the App. The web version works also fine on a tablet or phone, when WIFI is available (or 4G/LTE in an internet bundle)
Try to read and write in Duolingo's Spanish discussion forums. There you will find the daily used words, sentences and idiom.
Apart from that
- read a newspaper article every day and try to learn its new words
- listen to podcasts, watch movies with or without subtitles
- converse with a native speaker as much as possible
- write smaller texts, upload them on http://translatihan.com/ and let them be corrected by native speakers
- try "Duolingo stories" https://www.duolingo.com/comment/23206004
There are numerous possibilities. Duolingo will only bring you to an A2/B1 skill level in reading/writing and A1 (maybe A2) in listening/talking.
