After `Ricardo-Rick's calmness on my excessive questions on these, no I am able to read the letters properly. This work reminds me of the sketch designs my friend used to do before And props to you for using colours that's related to blue! (that's a plus for me). I was wondering if you scanned the image or not? Maybe you could edit it up a little to increase the brightness as the lower right part seems very unlit and the rings of the binders are a bit distracting, but that's fine i guess I like how the letters feel 3 dimensional, because of those small curves inside the letters during the turning points.
Reading graffiti seems to be a hard job for a significant percent of people, even if some of them are visual artist/painters. Sometimes is hard for graffiti writers to "decipher" letters made by another. It's a matter of style. Personally I'm in the "readable" zone, because I want it to be so.
Image is not scanned, i took a photo of it with my camera; I edited only the contrast.
