I can't say I liked your poem a lot. It's far too sentimental for my taste. There's too much tragedy and tears and passion in it. Watson is OOC. If it was written from the point of view of the real author, such feelings would have been understandable.
I think you use too many word repeats. I's ok if you use them once to make us pay attention to a sertain thought, but if this method is seen too often the poem resembles a pop song.
IMHO it would help if you paid a bit more attention to the word expressions you use. "Head" and "again" don't make a really good rhyme. I don't mean that "again" should be changed to "dead", for it would also be a silly and opbvious way out, and the ideal rhyme isn't what one must seek today. I think you could try to find out a more original way to express your idea. For now the lines sound rather naive. (A.S. Pushkin (a russian poet) once made a joke that upon hearing a word "rose" in a poem one expects the next line end with "frost" (in Russian trese ords sound similar: "rozy"-"morozy" And a paet should always try to find a word that none expects).
Your other lines could have some polishing too, methinks. Your language is overly expressive (you must be a really emotional person), but would it not be better if you didn't give all feelings straight away but made others guess by using symbols, allegories, etc. I don't ask you to write something "classical", in fact you can use 3 times as little words as you did. But your idea must be clean if you want others to understand it without using the unrewarding method of emotion.

I appologize, if my comment was rude. I'm not sure if I was right to tell you all this. I was studying literature before having turned to architecture.. Anyway, everything I said is pure IMHO, but I've written it because I see potential in you and know that you can improve your skills. I'm sorry if I made too many grammar mistakes. I'm not a natural English-speaker, as you must have figured out by now.

*stamps foot upon ground* NO! Really good poem but...but...AUGGH! WHY! Why! And since when did Sherlock Holmes do coke?

Beautiful stuff. I liked it alot. However, many people make too much out of Sherlock's cocaine addiction. (remember, he only injected himself when he needed a brain boost or when he was feeling bored/laconic etc.) Just a quick pointer, but your poem stands well on its own.

Wow... intruiging piece. A lot of the frustration that Watson seems to feel for Holmes in "The Sign of Four" coming out here. I think that Holmes' cocaine habit is one of the most intruiging facets of his character... that someone with such an incredible potential would turn to such a vice.

Great poem, loved the way it was srtuctured. What is it called, when you write a poem using the first letter of each line to write a message? I can't think of it...

Wonderful, my dear.

this is really moving
i like it

Oh! That was so sad! But it was brilliant! I can't see the screen, I'm crying so bad right now. Poor Watson! I like the acrostic part alot too. I can't wait to hear from you again!

Nice. I particularily like the bold-typed message.

Nice subliminal messaging. I particularly like the last line.

"Damnit, I may as well have jabbed the needle in his vein myself."

It was always a possibility. Dr Watsons dilemma. Well written POV.

personally, I would say that this isn't bad at all. Holmes dying of coccaine... well done!
