I am the designer that did your friend's logo design,Aussie Slotcars.com :)
will try to make your logo too :D

a question,any color requirements?any colors you love or we can use any colors?

Alexis,  Please see my web site  www.hcslots.com to get a feel for my products.  The logo should stand out but not be brash.  It will eventually be used on product packaging.  The stylized slot car you did for Aaron is very good.  I included some photos of cars I did to give you something to work with.  Generally your layout for Aaron is well balanced.  It has the feel of ''speed'' yet with a current look.  It is simple, clean  and draws the eye into the art.  As for colors, two colors plus a shaped black should be enough.  Colors should be somewhat bold/bright and not subdued/dark.    You can email me directly   tflynn7@verizon.net   Thanks,  Terry  

The stylized car in the logo needs to reflect the photos I posted.  Please do not use Aaron''s artwork. Colors might be bright mid-tone yellows, oranges, reds, blues.  But you may have better solutions.  Thanks,  Terry
