I will never fault anyone for honing their craft, but you posted this either for your own self gratification or you sincerely desired feedback on the design for future improvement. If the latter is the case, always remember that you are advertising to passing motorists. Simple, easy to read designs that capture their attention always produce results. The design lacks many of these elements. Sometimes, simple, to-the-point lettering and graphics work the best. Keep it simple concepts overrule software design capabilities. Just because you have the software to design intricate layouts doesn't necessarily translate into easily assimilated advertising. Food for thought. Have a great day!
