Whelp I don't really know how to work stuff in photoshop but the image is looking good!
As for the poem I do agree that there are emotions that you feel that cannot be expressed with words and just referring words as weapons is reminiscent to "Pen is mightier than the sword" phrase. Then you proceed with describing yourself as an assassin. So yes, words bleed and sting much more than the physical wounds acquired. Weird analysis(?) but I wanted to write something hopefully decent?
I was talking about this earlier, actually- there's words for every emotion you've felt, ever will feel, will never have the chance to feel... and then there's words for emotions too strong for words. Language is an art form, and poetry (generally using less words than prose) makes you choose your words well. Many times, as I write, I find myself as well to have "a tongue unworthy for poetry and / lips too vulgar for sweet nothings". I love those lines more than anything. You don't have to be as beautiful as your work to be a poet; but poetry reflects inner feelings, trials and emotions- so what "comes out" in your writing was in you all along. It's why they say that it is "coming out". c:
