Simple submersible sketched in a trial version of Autodesk Sketchbook Pro. Fantastic program, that is. Anywho, I realize that I haven't put very much art on this site. . . But this will have to do for now. Enjoy!
Oh, also: critique is welcomed! I'd like to know how I did on shading. . . I seem to have a problem with metallic surfaces. Thanks in advance for those who comment!
