I really like how you put it all together. The only issue at this point for entry #12 is the orientation of the race circuit is incorrect. I see how you re-orientated the race circuit to put the cyclist there, that is what I am looking for, but this race circuit is very popular the participants will know immediately by looking at the orientation the circuit is incorrect. Take a look at the jpeg and if you can correctly orient the loop with the cyclist riding in the same spot you will have the contest all wrapped up.
Thankw so much! But unfortunately I'm running out of time! The contest will be in judging mode in the next few minutes and during the judging mode, only the 1st ranked designer who could still submit revisions. Please give me a chance to submit the revisions by puting me at the 1st rank (even just for temporary) so I able to submit more entries. I'll do my best for you!
