我很自在

上个星期我毕业了!因为上课很费劲所以现在我觉得感觉很自在。虽然我有空了，但我不吃闲饭。我练习我的中文，还有我提高我做饭的水平。当然虽然我要做半日工作，但是我还是比较闲。

#It's very good,I think.

我很自在 心情很轻松

上个星期我毕业了!上课很费劲，所以现在我觉得很自在自在多了/很轻松。虽然我有空闲下来了，但我不吃闲饭。我练习我的中文，还有我努力提高我做饭的水平。当然我还是要做半日工作打工/上半天班，但是我比较闲了。

不自在 is “uncomfortable”/ “uneasy” while 不轻松 is “leaden” or “demanding”, so I suppose 轻松 suits better for the title. 

闲下来 signals there is a halt (also could be an endless one) to the busy life, but 有空 is usually within a certain period of time. 今天晚上有空  下个礼拜有空  这两个月都有空  现在有空

他还没闲下来。  他还没有空。

提高 is the goal here, so a verb like "want to" or "try to" is needed. Considering the previous sentence uses 练习, 努力 is recommended as it is already in progress.

打工：doing part-time jobs    上半天班：working for about half of the regular working hours
