The key features are 'hot girl' and 'mining' must be combined. Revealing clothing is idea. A greyscale photo would be ideal, however drawings, silhouettes, and anime style drawings may also work.
See attached photos and comments:
Photos 1, 2, and 3 - style of pose I want the girl going for. I also like the skimpy type clothes she is wearing. The tool belt is a nice addition. These photos are all good samples of what I want to replicate on the t-shirt. However, at least a mining pick must be visible.
Photo 4 - This is sort of what I want. But the pose should be less 'masculine' and more 'sexy'. The elements like the hard hat, skimpy clothes, and mine pick are there though.
Photos 5, 6, 7 - These are the style of t shirt I want to replicate. I'm sure you see alot of these on guys going out clubbing. Preferably I'd like a white shirt however if the design works on black, or any other colour then we can do that. Note the black and white colouring of the girl.
Photo 8 - Another example, except make the girl have a sexier pose and mining. The black and white works well.
Photo 9, 10, 11, 12 - Other good examples.
Photo 13, 14, 15 - Anime style shirts. Some examples. There should be emphasis on large breasts and a skinny waist
The intention is to produce several more shirts of similar style. Future 1-on-1 work may be offered after the contest.
