Hello Graphic gurus, I just finished this two jobs, I am doing it for someone that wants to hire me. please i need your opinion on the one that i should print out as sticker. thanks.

One of the reasons I'd go for the second one would be cos of the size caterpillar image. Good luck!

P.S: I'll suggest you change the contact info to black. And that region (including the motto region) could be white out.....also you could do away with the shadow on the company's name (else make the shadow a subtle white). Cheers!

nice start, unless the client expressly requested the image u used, i would suggest u change it....or atleast add another.
nothing about the design suggests training.
infact it looks more like an equipment leasing outfit.
an image of a man in safety gear may even be more appropriate.
my opinion, mind.

goodluck.
