The reason I rate this product so low is not the artwork. The artist shows promise and most of the (considerable number) of mecha are well executed.

The problem is the production values. These are pencil sketches on paper that have been scanned in. You can see the grain of the paper, folds in the paper, occasional pencil smudges, and in one case an uneven top of the page. This makes them poor options for using as clip art.

I certainly wouldn't mind seeing more of the artist's work, but only after he gets a drawing tablet or better scanning solution. Inking of the images would be good too, making them easier to clean up if you did want to use them for clip art.
