This looks decent from a distance, but close up its a bit more clear that you've roughed out the main areas and shapes of interest, then filled empty space with different shaped squiggles and random line patterns to make it appear more detailed. Some of them are words, but it results in the same effect, like you're trying to trick the viewer into thinking an image has a great amount of detail when in reality id doesn't have much substance. I'd recommend working on your forms and figured before trying to create a piece overwhelmed by detail. Witherwise, it is interesting to look at, keep it up!
