Hello everyone! Here's the concept - a fishtank on wheels that you can drive across the bottom of the ocean, into a volcano, through a Garth Brooks concert, any hazardous environment imaginable. Inside is enough space to construct a small town. Basically the ultimate version of the RV from The Wild Thornberries. I need to improve on crosshatching and involving more dark values to define shapes. I am going to transfer to a piece of watercolor paper and try something I am more comfortable with. Any thoughts or suggestions appreciated. Thanks
