Good job! Especially for your first try and being a non-English speaker. I applaud your efforts in translation to share your story with us.
A very cute idea, Lois thinking Clark was going to commit suicide.
I too liked you described how tired he was and that his *battery* finally wore down and he couldn't fly anymore (it was dark and there was no sunlight to recharge him). Neat idea. And I liked the part where Clark told her to look at him, to really look at him... nice.
