Corporate Christmas card

Designer needed to design a corporate Christmas card. Attached is an example of one that was done last year, this was done at the last minute and we are looking for something more creative this year but equally simple. The company is within the financial services sector and the card needs to feel professional and corporate but put a smile on someone's face when it is opened.
The card should feature the turtle with something festive (using the turtle from the logo but it can be modified slightly if needs be). For instance, the turtle underneath some mistletoe, the turtle could be holding a present, the turtle could be putting up a stocking etc...
No photos to be used, not to feel cartoon like, drawing / design / illustration only. This is a corporate card. Image inside to read something along the lines of 'Wishing you a very Happy Christmas and a Wonderful New Year' with the logo at the bottom.
Please show examples of your work when applying.
