Chosen three thumbnail sketches to develop

My chosen design which I have put into blocked colour

The design which I have developed a little bit more using textures and a range of photo shop tools.

The final design with outlines however it looks scruffy and very messy.

These images show some of the development of my shield for my character, I think the color scheme of the shield however I need to clean up the lines around the shield in order to finish the design off, which I am going to look into and also a few other sketches to finish off the prop.
