Here's my entry for the thumbnail contest. It is the same as the one I created for the logo contest, however I have changed the dimensions to suit the thumbnail size specifications. Hope this is considered as a valid entry. If not, let me know, I'll try something else :)
It is totally acceptable. Although I will add that we are hoping to have a different yet similar thumbnail.
I will work on a shortened version of this one then! Thanks @bambam808 :)
