This picture is so adorable! I really love Trent's outfit and Gwen's expression.
Reading the comment about Trent's 'odd' appearance and seeing as you didn't get any input I decided to reply.
The only thing odd about Trent is the size of his head and the sizing of his eyes. Usually younger kids tend to have much rounder faces and softer features. Most of the kids in total dramarama have rounder faces and much bigger eyes especially compared to their original total drama island designs. I think if you used Gwen as a sort of template to place Trent's features he would look more childsish and fit in.
Just my 2 cents, I am so sorry if I happen to offend you in any sort of way. But that's from experince trying to draw a baby and it's head was egg size large but making it rounder yet smaller in size made a huge difference.
