Don't know if I completely agree with Jon. Tone on tone is a style with little contrast which can look great if done well and sometimes a dark design on a dark shirt can look great. I do think this design would look better without the bevel effect. Cool idea to have the cross knocked out in the 1.

Interesting design. One side note though, when you're working with dark colored shirts, try making the design a bit brighter in this case. There's not enough contrast between the shirt and the design.
