Welcome to the Guild Crossbuilder! This is looking pretty good so far. I agree with Gidde that you have chosen your fonts well. Usually I don't think that it is a good idea to combine hand drawn features (and icons) with patterns or fractal clouds since the two styles usually don't complement one another. But in a black and white piece like what you've done with the sea seams to work alright.
