Why are the hex shafts so long? Just curious, I'm sure its just something you haven't gotten to yet.
Looks good. Designing in sheet metal is a very good thing to learn if your planning on becoming a mechanical engineer of some sorts. I cannot tell you how many sheet metal parts I've designed for my various jobs I've had. It comes in handy for other parts too that aren't necessarily made of "metal" (ie: polycarb, other such plastics) which may be created using the same techniques as standard sheet metal parts.
Also very handy with sheet metal are PEM fasteners. If you can master their usage, you can create really sleek sheet metal designs.
Have you done any FEA on the frame? Its sometimes difficult to gauge the "strength" of a design from sheet metal, especially when first starting to design in sheet. My only comment would be to add a cross member lower on the frame to add another axis of stability, however it may be unnecessary, thats what analysis is for!
