Hi! This isn't that bad in intent, it's just pretty awkard in execution.
"Here on a craggy mountaintop I stand,"
Look at "craggy." It's about as cliched an adjective" a "wind swept." Look beyond that: How badly would it hurt, or help, to specify the mountain?
"Here at the World’s desperate and lonely end;"
What World? What "end," why "desperate," how "lonely?" The thought is there, the words are basically meaningless. And no semi-colon, just a comma.
"The swollen clouds hold my embittered hand,"
OK, we can take that for a metaphorical image, though it makes not literal or poetic sense.
"The lightning is an only trusted friend;"
Sucky friend, man, it's gonna kill ya if you trust it too much.
"The Sky so near, the World so far away
I forget all lowly and earthly things;
The humble passings of a normal day,
The arrogant pomp of unquestioned kings."
Ok, now we get to the poem, you are standing on some mountain top, detached, observing.
The remainder is abysmal.
Now, there is no real problem in writing something abysmal. Most of us do it all the time. The problem lies with not editing the abysmal, or editing the abysmal out.
There is something you want to express here. You don't do it, except, of course in the way that you do do it. Which doesn't work.
My suggestion woud be to go back to this theme, which has a kind of validity, and say what you want to sat, not what you think you ought to say.
