Assault rifle final with variants

This was an an experiment to expand my portfolio and try and go through the process of concepting .By doing this it was clear to me that thumb nails are a key part of concepting not only for myself but for your client.
When i was coming up the with the design for this i was drawing in ball point pen on a piece of yellow stripped paper which you could show to a client but it may be a point where they are unable to give you feed back because they dont see what you see hidden in the lines and the mess.Because of this i have been practicing doing pages of themed thumb nails on plain paper.
As I move onto the next exercise i will make sure i am able to present my work along the way in some fashion.nothing fancy but something that conveys some clear ideas.What may seem like chicken scratch to me is a valuable tool in creating a pleasant interaction between you and your client .

any way yes Assault rifle ! The original was painted in grey scale with acrylics then scanned and cleaned up colored and rearranged in Photoshop.
